Freshwater Dips For Saltwater Fish 

Putting a saltwater fish into freshwater may seem like a risky move – and it is if done incorrectly – but when done properly, it can be useful in removing parasites like Flukes and some Protozoans. The keys here are preparation, timing and observation. It isn’t as easy as dropping your clownfish into your goldfish tank! You can use this method for new arrivals before adding them to your tank or to treat fish from a display or quarantine tank.

1. Prepare your dip container and water. The container should be clean and free from any detergents or waste and large enough for your fish to swim comfortably. Use clean, dechlorinated freshwater that is the same pH and temperature as your aquarium….this is key! You may need to use a buffer like baking soda or high range buffers for African cichlid tanks to raise the pH to match your aquarium, but make sure it is as close as possible. Adding your saltwater fish to freshwater with a much lower pH (for example, a neutral 7.0 when your aquarium pH is 8.4) is very stressful.

2. Once your water is prepared, carefully move the fish from the aquarium into your dip container. If you are using a net, be especially careful around any fish with spines that may get caught or damaged.

3. Continue to observe your fish in the dip. If you see (or suspect) parasites like Flukes, you can use an eyedropper or turkey baster to gently blast water onto your fish to help knock off any parasites.

4. If you notice any strong signs of stress, remove the fish from the dip and get it back into saltwater right away. Otherwise, a minimum of 5 minutes will help remove most parasites, and most fish can typically tolerate a dip up to about 10 minutes.

5. The dip water can be reused for several dips if you have multiple fish to treat, but dispose of the water after you are finished and rinse your container for next time. 

Dipping Corals

Dipping corals can help remove pests and parasites as well as treat a number of infections and conditions. Many brands of coral dip solutions are available on the market and typically use ingredients like botanical oils to kill or dislodge pests from corals. Iodine can also be used in some situations, especially when treating new frags or damaged colonies with tissue that can be vulnerable to infection. When choosing a dip, be sure to read the instructions as some dips can’t be used on some types of corals and concentrations or timing can vary from brand to brand. The instructions here are a basic guideline for most corals and dips.

1. Prepare the containers for your dips. These dips should always be done in a separate container but can usually be done with either water from the tank (if you can safely remove enough for the dip) or with freshly prepared saltwater. The container should be big enough to completely cover the corals being dipped but doesn’t need to be larger than necessary to avoid wasting your dip to reach the proper concentration.

• Depending on the dip and concentration you are using or the corals you are dipping, you may want to prepare a second container to “rinse” your corals after the dip. This should be about the same size and amount of water and can also be either tank water or fresh saltwater.

2. Add your dip solution to the water before adding the coral. This makes it easier to mix the solution throughout the dip container without dumping it directly onto the coral. Most dips have recommended concentrations like 1 teaspoon per gallon of water but can usually be adjusted depending on the coral; use a weaker solution for more sensitive or stressed corals or stronger solution for resistant pests or very hardy corals.

• For Iodine dips, you can use the color to determine the strength. On a white background, a weak Iodine solution should be about the pale tan of a manila envelope. A strong Iodine dip would be a rusty red-brown but the corals should still be visible. Avoid a concentration so strong that you can’t see through it.

Iodine Dip Concentrations

3. Add the coral to the dip and follow the instructions on your dip. Most corals can be dipped for 5-10 minutes but if the coral appears very stressed or starts releasing a lot of slime, remove it from the dip. Hardy corals like polyps or milder solutions may be dipped for longer.

4. After the dip, rinse your coral in the dip by gently “swishing” it around underwater. If you prepared a rinse container, you can do the same in this container as well. This is especially useful after strong Iodine dips or with especially mucus-y corals.

5. Replace your corals back into the tank and dispose of your dip and rinse containers….don’t add this water back into your tank! 

When done properly, these dip methods can help keep your tank parasite- and pest-free without the need to medicate the entire tank, or to supplement a medication regime. Feel free to contact us if you aren’t sure if a dip is right for you!

Some History

The waters around the Hawaiian islands are some of the most unique habitats on Earth. According to the National Oceanic and Atmospheric Administration (NOAA), an average of 21% of fish species above 100 feet deep and up to 50% of fish between 100-200 feet deep are endemic to Hawaii, meaning they are found nowhere else in the world^[1]. Many other fish that are also found elsewhere may have different color variations around Hawaii or nearby islands. They face some unique challenges as tourism grows and habitats shrink, however. Overfishing and habitat loss threaten some populations and recreational activities like fishing, snorkeling, boating and others can damage reefs and their inhabitants. Naturally, such an important part of Hawaii’s economy and natural history needs protection.

As the aquarium industry grows, so does the concern about its impact on the environment. In recent history, this first began seriously intersecting with Hawaii’s preservation efforts in 2017. In September of 2017, the Hawaii Supreme Court halted the renewal of all aquarium collection permits pending an environmental review of the practices used and their impact on native populations. Prior to this ruling, collections were allowed by permit using fine mesh nets (HRS §188-31^[2]). Over the following year, this statement was revised and expanded^[3] but live collections continued in smaller capacities. Other activities like spearfishing did not appear to be impacted. In August 2020, the aquarium collection industry took another hit when an impact statement from a number of aquarium fish collectors and the National Pet Industry Joint Advisory Council was rejected by DLNR^[4]. As of January 2021, the DLNR announced that not only were permits no longer being renewed but all existing permits were invalid and all collection was halted indefinitely pending environmental review^[5].

The actual impact of aquarium fisheries on populations has long been debated and is extremely controversial for both sides. The Marine Aquarium Society of North America’s Hawaii Ban Fact Check page^[6] argues many of the ban proponent’s claims. In one study cited on the page, the impact of aquarium fisheries compared to recreational fisheries and commercial food industries shows the high value and low impact compared to recreational and commercial food fisheries. It also cites a growth in the population of popular aquarium fish like Yellow Tangs and Kole Tangs in the most common collection areas despite the increase in fish being collected from these areas for the aquarium industry^[7].

So…what now?

While this ban is in effect, don’t expect to see Hawaiian fish^[8] like Yellow Tangs, Kole Tangs, Achilles Tangs, Potter’s Angels, Fisher’s Angels, Flame Angels, Blonde Naso Tangs and many more. We have seen the prices of these fish increasing in price and dropping in availability since the early 2010’s and those prices have tripled just between fall 2020 and January 2021. A Yellow Tang that we may have been sold for around $65-70 in October would have sold for $400 or more in January 2021, and we’ve seen some other online retailers advertise them for over $1000.

Due to their breeding and life cycles, many of these species are incredibly difficult to breed in captivity. While a few breeders are just starting to figure out some species like Yellow Tangs, we are a long way off from seeing them as commonly as easier fish like clownfish, and they are still very small and expensive when they are available.

What are some alternatives?

While these species may not be seen in our tanks anytime in the foreseeable future, there are alternatives to give you a similar look or function. These three species in particular are just the most popular fish affected by this ban. Some of these alternatives do have different size ranges, care requirements and compatibility guidelines than their inspiration so be sure to research all choices carefully.

• Yellow Tang (Zebrasoma flavescens)
  • Yellow Pygmy Angel (Centropyge heraldi)
  • Yellow Longnose Butterfly* (Forcipiger flavissimus)
    • *This species is also found in Hawaii but is also found in other areas of the Indo-Pacific. Hawaiian fish may not be available but fish collected from other areas may be.
  • Foxface and Rabbitfish (genus Siganus) – Many different species are common. Some like the Blotched Foxface (Siganus unimaculatus) have an almost all-yellow body like the Yellow Tang
• Kole Tang (Ctenochaetus strigosus)
  • Twospot Bristletooth Tang (Ctenochaetus binotatus)
  • Lined Bristletooth Tang (Ctenochaetus striatus)
• Moorish Idol (Zanclus canescens)
  • Bannerfish (genus Heniochus) – Many different species have a similar appearance to the Moorish Idol. The Longfin Bannerfish (Heniochus acuminatus) in particular is very similar to the Moorish Idol. In fact, it was once referred to as the “Poor Man’s Moorish Idol”.

Many other species that are endemic to Hawaii will disappear from the aquarium industry for awhile, and others that are native to Hawaii but also found elsewhere may become scarce or increase in price. If you can no longer find your Dream Fish after this ban, feel free to let us know and we can help you find it or recommend some alternatives.

How Much Does That Aquarium Cost? That Fish Blog

Springtime = Pond Fish Time!

At our retail store in southcentral Pennsylvania, there are a few things we can always count on as soon as the temperatures start to rise: that particular fragrance as farmers get their fields ready for planting, new road construction projects, and our pond customers to start looking for new pond fish and plants for their outdoor ponds. However, those first warm days of the year aren’t the best time to start stocking your ponds. In our area in particular, the first warm days don’t mean it will stay warm. It is pretty common during a Pennsylvanian spring to have sunny 70 degree days followed by chilly 30 or 40 degree nights and even snow flurries. Even if it is warm during the day, that is only the air temperature…water temperatures and ground temperatures take far longer to warm up and stay a consistent temperature.

Springtime is one of the more dangerous times of the year for new and old pond fish alike. Moving fish that are kept in a climate-controlled indoor system like our retail store to an outdoor pond with cooler and inconsistent temperatures leaves them extremely vulnerable to stress and secondary infections like the dreaded Aeromonas bacteria. Fish already in a pond that are “awoken” from their winter dormancy by the warm temperatures are also vulnerable as the water temperatures affect their metabolism and immune systems.

So when should you add new pond fish and plants or “open up” an existing pond for the spring?

Keep an eye on the water temperatures and wait until the temperature is consistently above at least 50-60 degrees. Do not feed any fish already in your pond until water temperatures have stabilized above 40 degrees as your fish will have trouble digesting food in cold temperatures, and use a Spring and Fall Formula fish food that is easily digested until your ponds temperatures have stabilized above 60 degrees. For plants, wait until any danger of overnight frost has left your area. Weather websites like AccuWeather.com often have Lawn & Gardening sections that can help you determine when the best time is for your area. It may be necessary to wait even longer for more tropical, warmer-water plants like the popular Water Hyacinth.

While the weather conditions in your area may vary and the seasons are always a little different every year, we’ve found that for our area, May 1st is a good guideline for the safety and health of the fish and plants. This is also around when many hatcheries and nurseries start having the best stock available as well so we can get you the best variety and healthiest stock possible!

History of Goldfish in the US

A western aquarium of the 1850s illustration from Shirley Hibber, The Book of the Aquarium and Water Cabinet

Goldfish are freshwater members of the carp and minnow family.   While many of us admire them from the view of our tank, they are actually one of the first aquatic invasive species to reach North America.  How did the goldfish go from being the cute googly eyed fish you would feed after school, to being such a widespread risk to native plants and species?

Goldfish began to come to the America’s in the 1600s as ornamental fish for aquariums and water gardens. If the fish became too large for their surroundings, or the owner became tired of it, they simply got rid of it in the closest freshwater source.  Today, goldfish are becoming reintroduced as livebait.  Pennsylvania has stepped in, as well as many other states to make it illegal to use goldfish as live bait.

The Real Issues

Goldfish (Carassius auratus) photo by Ontario Streams

Goldfish will typically eat their own eggs when held in captivity, so breeding is not a large issue for most hobbyists unless they are intentionally breeding their goldfish.  Given the right conditions, goldfish can spawn several times a season.  A lot of the eggs will get eaten by the adult goldfish once they are laid, but several hundred eggs are produced at each spawning.  With only a few eggs eaten, and fry hatching within 48-72 hours, you can imagine how just a few goldfish can turn into a large problem rather quickly.

Often referred to as the “little piggies” of the aquarium, goldfish are opportunistic feeders and will not stop eating of their own accord.  While goldfish typically feed off of crustaceans, insects, and various plant matter; when this food is scarce they will eat eggs from native species nests.  The native egg-laying species populations have now been disrupted, and due to that, the population has declined and disrupted other wildlife food chains.

Law on the Books

It is unlawful to use or possess goldfish, comets, koi and common carp as bait fish while fishing in the state of Pennsylvania. If you are caught fishing with feeder goldfish or any other illegal bait fish there is a minimum $120.50 fine, and you can be fined an additional $20.00 – $50.00 per illegal bait fish.  Pennsylvania Fish & Boat Commission wants you to know that you aren’t off scot-free just yet.  Law enforcement also has the authority to confiscate or seize, any fishing equipment as evidence of your violation of the law.  The Pennsylvania Fish & Boat Commission may, upon proper notice, suspend or revoke your fishing privileges, boating privileges or other permits of any person convicted (or acknowledging guilt) of a violation of the Fish and Boat Code or Fish & Boat Commission regulations.  That would also include your naive fishing buddy.  Should multiple violations occur within a 12-month period you will be given a fine of $200 in addition to the previously mentioned summary offenses.  That $0.10 feeder fish now cost you a fishing license, a fishing rod, fishing equipment, a whole lot of cash, a boat, and a fishing buddy. The consequences per state will vary, so check with your local Fish & Boat Commission for more information.

The employees at That Fish Place – That Pet Place are all avid hobbyists, and a lot of us live in the local river towns where fishing is just a way of life.  We don’t want to ruin the sport for other enthusiasts, just as much as we don’t want others to ruin the sport for us.  We will always strive to do our best when it comes to conservation efforts, and want to encourage others to do the same.  Thank you for reading!

The fish and other sea creatures featured in these movies are, first and foremost, saltwater animals. That means they need a saltwater aquarium. This isn’t as easy as putting some table salt in your home aquarium. The water has to be mixed to the correct levels (Specific Gravity 1.020-1.024) in a separate container before being added to the aquarium. Most of these creatures are also tropical, which means the tank needs a heater to maintain warm water temperatures (75-80 degrees F). The décor of saltwater tanks is usually different than freshwater as well; unfortunately, ornaments like Mount Wannahockaloogie just don’t work very well in saltwater aquariums. Most saltwater aquariums use natural crushed coral substrates and live rock although non-animated decorative ornaments are usually safe. For more information of basic aquarium care, visit our Saltwater Aquarium Basics Guide.
So what about the fish and other animals? Some of the movies’ characters are obviously impossible and even illegal to keep in home aquariums. Others are very difficult while some are very common and easy for hobbyists to care for. We are only going to discuss those characters here that are within the scope of our hobby.
( ❶ “Finding Nemo”, ❷ “Finding Dory”)

Hippo Tang (Paracanthurus hepatus)

“Dory” and her parents: Hippo Tang (Paracanthurus hepatus) ❶ ❷

Max Size: 12”
Minimum Tank Size: 150 gallons
Difficulty: Moderate
The Hippo Tang is a fairly delicate fish with a weak immune system. They also grow too large for many aquariums. Although tempting, only experienced aquarists with larger, established aquariums should attempt this fish. Like other tangs, Hippo Tang can become very territorial and only one should be kept per tank.

For more information on keeping Hippo Tangs, visit our Tangs & Surgeonfish Care Guide. 

“Nemo” and “Marlin”: Clownfish (probably Amphiprion ocellaris) ❶ ❷

Ocellaris Clownfish (Amphiprion ocellaris)

Max size: 4”
Minimum Tank Size: 20 gallons
Difficulty: Easy
We could debate about exactly which kind of clownfish are featured in these movies, but they are probably Ocellaris Clownfish. Percula Clownfish are also very similar in care and appearance (they just develop thicker black margins). Clownfish like these are some of the easiest saltwater fish to keep and can be kept in much smaller aquariums than many of their costars. Captive-bred fish are much hardier and better for the environement than their wild counterparts. Their anemone home is much more delicate however and has some much more intensive requirements. Most clownfish – especially captive-bred – don’t need an anemone to be happy and healthy.

For more information on keeping Clownfish, visit our Clownfish Care Guide and Clownfish and Anemone Preference Guide.

Common Octopus (Octopus vulgaris)

“Hank”: Octopus (Octopus sp.) ❷

Max Size: Depends on species
Minimum Tank Size: 30 gallons for small species
Difficulty: High
Octopus are very specialized and difficult to care for and need a specially built aquarium to keep them from escaping like Hank so often does in “Finding Dory”. They will also eat almost any tankmates they are kept with. Only expert aquarists should attempt an octopus.

“Gill”: Moorish Idol (Zanclus canescens) ❶

Moorish Idol (Zanclus canescens)

Max Size: 7”
Minimum Tank Size: 75 gallons
Difficulty: High
Although not as delicate now as they were even when “Finding Nemo” was first released, Moorish Idols are still difficult to maintain for long. It is difficult to keep these fish healthy through collection and it can be tricky to get them to eat in home aquariums. It is best to stick with hardier lookalikes like the Longfin Bannerfish (Heniochus sp.) for new or novice aquarists.

Porcupine Puffer (Diadon holocanthus)

“Bloat”: Porcupine Puffer (Diodon holocanthus) ❶

Max Size: 20”
Minimum Tank Size: 200 gallons
Difficulty: Easy to Moderate
Although these puffers are usually only a few inches in length when they are sold for aquariums, they can grow to almost 2 feet long! Puffers also have very strong beak-like teeth and can crush through shells. Unfortunately, most of his tankmates in Dr. Sherman’s office wouldn’t have survived being kept with a puffer. Puffers “blow up” as a stress reaction and, while comical to us, this is very stressful and even dangerous to the puffer and should NEVER be provoked for any pufferfish.

“Peach”: Starfish ❶

Red Knobbed Starfish (Protoreaster lincki)

Max Size: Depends on species
Minimum Tank Size: Depends on species
Difficulty: usually Easy
It is difficult to tell exactly what kind of starfish Peach is but most of the thick-bodied starfish like her are fairly easy. However, most of these also eat snails and other inverts so use caution when choosing your starfish and its tankmates. They are sensitive to water quality and changes in water quality so make sure the tank stays clean and stable.

Royal Gramma Basslet (Gramma loreto)

“Gurgle”: Royal Gramma Basslet (Gramma loreto) ❶

Max Size: 4”
Minimum Tank Size: 30 gallons
Difficulty: Easy
Royal Grammas are colorful fish found in the Caribbean and western Atlantic Ocean, unlike the Pacific homes of most of the other fish in the movies. They are hardy and easy to keep, but can be territorial. Only keep one basslet in the aquarium unless it is very large with lots of rockwork.

“Bubbles”: Yellow Tang (Zebrasoma flavescens) ❶

Yellow Tang (Zebrasoma flavescens)

Max Size: 8”
Minimum Tank Size: 75 gallons
Difficulty: Easy
Yellow Tangs like Bubbles were some of the first to be kept by home aquarists and are still some of the most popular. They are hardier than tangs like the “Dory” Hippo Tang but are also more aggressive. Once they establish a territory, they will not tolerate other tangs – or possibly even any other fish – entering it. Only keep in a large tank without any other closely-related tangs or closely-colored fish.

4-stripe Damsel (Dascyllus melanurus)

“Deb”: 4-stripe Damsel (Dascyllus melanurus) ❶

Max Size: 3”
Minimum Tank Size: 30 gallons
Difficulty: Easy
Damsels like Deb are some of the hardiest and easiest saltwater fish to keep. They are usually recommended as the first fish for any saltwater hobbyists to attempt. Most damsels can get very territorial however so make sure the tank isn’t overcrowded and there is plenty of territory for these fish. The 4-stripe Damsel specifically is one of the milder-tempered of all damselfish.

“Jacques”: Skunk Cleaner Shrimp (Lysmata amboinensis) ❶

Skunk Cleaner Shrimp (Lysmata amboinensis)

Max Size: 3”
Minimum Tank Size: 20 gallons
Difficulty: Easy
Like Jacques, shrimp like these will clean parasites and dead scales off of other fish, but they will also eat almost any other food they are given. They are some of the easiest shrimp to keep but, like the starfish, need stable and pristine water quality. Shrimp molt their shell to grow so it is common to find an empty shell every now and then. Don’t keep with predatory fish (like pufferfish, for example) as shrimp are often easy prey.

Seahorse (Hippocampus sp.)

“Sheldon”: Seahorse (Hippocampus sp.) ❶❷

Max Size: Depends on species
Minimum Tank Size: at least 30 gallons for most species
Difficulty: Moderate to High
Seahorses are easy now than years ago and captive-bred seahorses are becoming more and more available. They are still very delicate though and keeping them with any other tankmates is difficult. It is best to keep them in a seahorse-only tank and by advanced aquarists only.

“Tad”: Yellow Longnose Butterfly (Forcipiger flavissimus) ❶❷

Yellow Longnose Butterfly (Forcipiger flavissimus)

Max Size: 9:
Minimum Tank Size: 100 gallons
Difficulty: Moderate
Because of their very thin “beaks”, it can be difficult to get these fish to eat in home aquariums. They need small food items at least once or twice a day. They may also eat some corals as well as the tubed feet from starfish and sea urchins.

 
These characters are just a few of the sea creatures that Disney’s revolutionary “Finding Nemo” and “Finding Dory” franchises have brought to the forefront of the both the aquarium hobby and pop culture, but they are the most suitable for aquarium life. If you choose to bring any of these movie stars into your home, choose carefully so you can give them the best home possible. Remember, as Bruce and his crew have taught us, “Fish are friends”!

L: Baby Tears (M. umbrosum)
R: Pearl Grass (H. micranthemoides)

“Baby Tears” vs. “Pearl Grass”

The two most common “Baby Tears” available to aquarists are Hemianthus micranthemoides (also called “Dwarf Baby Tears” or Pearl Grass) and Micranthemum umbrosum (the species most often known as Baby Tears, also called “Giant Baby Tears”). The main difference between these two plants is in the leaf shape. M. umbrosum (“Baby Tears”, from here on out) generally has round, almost completely circular leaves. H. micranthemoides (“Pearl Grass”, for the rest of this blog) has elongated leaves, more tear-dropped or elliptical in shape.

Both of these plants have almost identical care and can usually be used interchangeably but there are some small differences here too. Baby Tears is usually easier to care for and tends to grow a bit faster than Pearl Grass, but Pearl Grass is a better foreground plant that will stay shorter and have smaller leaves under high light. Baby Tears tends to be taller and bushier but either can be pruned and trimmed to maintain a height or growth pattern. Both plants can be grown in bunches or on a surface like driftwood, rock or a plastic mat to form a thicker carpet; use fishing line or string to hold it in place under the roots start to attach.

A thick mat of Glossostigma in an aquarium

Glossostigma: A Third Look-alike

Another plant, Glossostigma elatinoides (usually shortened to “Glosso”) is also very close to Baby Tears and Pearl Grass in appearance and is sometimes confused with these two plants. It has pairs of small, round leaves that are somewhat in between Baby Tears and Pearl Grass in shape, a rounded teardrop but with the widest and roundest part of the leaf at the end rather than by the stem. They stay short and small under very high light but the leaves will become bigger and taller under lower light. This plant can also be planted in the same way by attaching it to a hard surface or planting each stalk individually until it begins to spread on its own.

Oct 2016 UPDATE: Recent publications have listed that the Pearl Grass found in the aquarium trade may correctly be Hemianthus glomeratus, not H. micranthemoides. Though these two plants are very similar, they have some slight differences in native range and in the flowers. H. micranthemoides may actually be essentially extinct and it is thought that the Pearl Grass known to aquarists in the recent hobby is likely H. glomeratus.

Plant Profile: Baby Tears vs Pearl Grass That Fish Blog

I just got back from a long awaited vacation to Australia, part of which I spent in Northern Queensland, where I was able to make a couple of visits to the outer reefs for some amazing diving and snorkeling fun.  Having been born in Australia, and still being an Australian citizen, there are questions that I have been asked all my life from friends and acquaintances. Have you ever seen a Kangaroo? Have you ever held a Koala Bear? What the heck is Vegamite?  Yes, I have seen a Kangaroo, and held a Koala, and Vegamite is an Aussie thing that defies description, if you know, you know.  The question that I have been asked a million times over the years that I have always had to answer “NO” to, I can finally answer “YES” to. YES, I have been diving on the Great Barrier Reef.  I have been a certified diver for 16 years, and ever since I began thinking about diving, the Barrier Reef has always been one of my target sites.

The reef was everything that I had hoped it would be, truly amazing.  I have done many interesting dives, mostly wreck diving in the Carolinas, and some diving in Florida and the Caribbean.  It just does not compare. The shear size of the Barrier Reef is overwhelming, you could spend a lifetime exploring, and still only see a small portion of it.   The pictures that are posted in the blog are from my trip out to the Agincourt Reef System, which is a portion of the outer Great Barrier Reef system about 40 miles off shore out of Port Douglas, Queensland

You could tell that I was the only reef geek on the dive boat.  While most of the divers on my boat were hoping to see a shark, or a turtle, or maybe a migrating whale (don’t get me wrong, I would have loved to experienced a dive with a whale), I spent most of my time in shallow water, looking in all the nooks and crannies, taking pictures of “nothing” as I heard someone say.  The diversity was amazing, and some of what I saw was quite surprising to me.  There were huge colonies of brown Sarcophyton and Lobophytum leather corals, growing very near the surface, and large colonies of White Pom Pom Xenia on the outer reef.

A couple of the things in particular that I was looking forward to seeing were some wild Clownfish, and Giant Clams, neither of which I have had the opportunity to see here in the Atlantic.  The reef delivered big time.  I saw some massive T. gigas clams that had to have been at least 4′ long, as well as T. maxima, T. crocea and T. squamosa.  Some of the clams were in fairly deep water, one of the T. gigas that I saw was in about 50 feet of water.

Clownfish litter the reef, wherever their host anemones can gain a foothold.  Common to many of the large coral boulders were clusters of Green Bubble Tip Anemones (E. quadricolor), which hosted mostly Clark’s (A. clarkii) clownfish, and also some Cinnamon (A. melanopus) clowns.  There were also quite a few spots where what I believe were Long-tentacle (M. doorensis) Anemones hosting mostly Clark’s and a few Maroon (P. biaculateus).  The most spectacular anemones that I saw were a few bright blue and purple colored Magnificent or Ritteri (Heteractis magnifica) Anemones hosting Pink Skunk Clowns (A. perideraion).  There were others that I caught glimpses of, but I was not sure of the species.

The large schools of fish that dart about the reef are equally impressive, one of the more brilliant schools that I saw was one of hundreds of Yellow and Blueback Fusilier (Caesio teres), which are quite common to the reef.  Also seen on the reef were large schools of Green Chromis that dart in and out of the reef formations as they sense danger.

I hope you enjoy the pictures from my visit.  I think that this experience needs to appear on my list a few more times, as once was definitely not enough.

You may check out lots more underwater pictures I took of the GBR at the That Fish Place Facebook page.

Dave’s Bucket list and the Great Barrier Reef That Fish Blog

A few years ago, we moved into a house that had a small pond in the front yard. It was one of those rigid, preformed round ponds about 15 inches deep with a  50 to 80 gallon capacity. We kept a few goldfish in there the first year. They grew and made it through the winter just fine as we expected.

The following Spring, I got hold of some Astatotilapia aneocolor from Lake Victoria, 2 males 3 females to be exact. I was told by the previous keeper that they were aggressive, so I put them in a 55 gallon. I figured that would be plenty of space, since they were only 2.5 inch fish, and that they would leave each other alone for the time being.

Boy, was I wrong. One of the males showed his dominance within 2 hours of being added to the tank, and no matter what I did he couldn’t be swayed. I moved decorations around, gave him a time out for a week in a net breeder, and  I even put him into an aquarium with four 3 inch Black Belt Cichlids hoping he would be intimidated into submission. He went nuts in that tank, too, and started beating up the Black Belts, so back into the original tank he went. He quickly went back to his old ways, dominating and terrorizing the other male. He finally ripped out male no. 2’s right eye.

The Great Outdoors

I wasn’t sure what I could do for him. Then it occurred to me that I did have another place for him to go. The temps were high enough outside, so why not? I decided to relocate One Eye to the pond outside to give him a chance to recover. I watched to make sure that the other fish (goldfish) didn’t bother him and they didn’t. In fact, by the end of the week ol’ One Eye was the sole proprietor of the pond.

For the next few weeks, he ate well and still came up to the surface to see who was around the pond when I went to feed. I only had a little internal filter system on the pond, and soon the water started turning green. Before long I could barely see One Eye to see his condition, but i knew he was still alive and growing, possibly even larger than the bully inside. He was eating well, besides my offerings he ate insects that fell into the pond, and I also noticed he was scraping algae off the sides.

Meanwhile the dominant male in the 55 was attaining his astounding breeding colors. He was red on top half of his body and yellow on the bottom half with black fins.

The nights started to get into the mid 60’s, so it was time to bring in ol’ One Eye. When I netted him out I was shocked to see that he was an inch and a half larger than my dominant male and his colors were unbelievable! He had a deep maroon upper half and the bottom half was gold…I kid you not. I mean it was so vibrant that I couldn’t help but wonder what would happen to other fish from my collection if they had the same conditions. The following Spring, I upgraded the filter setup to an internal mag drive pump pushing into a Fluval 403 canister filter with the return line feeding a waterfall. I started keeping Albino Eureka Red Peacocks outside in that pond after the upgrade. You can see the results in my photo (top photo, sorry it’s a little blurry).

There is no match for the magic of natural sunlight and the varied diet tropicals can get outside. A friend of mine kept Red Terrors outside, where they bred for him through the season. Summer vacation outside isn’t just for cichlids, it can also be done with platies, swordtails, guppies and pretty much anything tropical if you have a place for them. Even small patio ponds could be populated with livebearers or tetras. Imagine a school of Cardinal Tetras soaking up those sun rays! Any pond will do as long as it doesn’t get too hot or too cold, and as long the fish have a little cover to protect them from would be predators like herons.

It’s a Jungle Out There

While the benefits are great, there are also some cautions to consider. This time I’d like to talk about some of the dangers and pests that may wreak havoc on our poor little fishies.

I was lucky not to have my pond visited by pests, but local stray cats, opossums, raccoons, snakes or predatory birds that may decide to visit your pond at any time.  Even bugs like dragonfly nymphs can prey on young and small fish. Ample water movement and surface ripples are usually enough to deter them, but more effort may be needed to deter larger predators. There are some easy ways that you can help to protect your fish while they enjoy their outdoor summer vacation. Personally, I would recommend the live plants. You can use floating foliage like water lilies, duck weed or hyacinths for cover and protection for your fish. Young fish will also hide in the roots and feed on the small bugs that live in the roots. Another solution is the use of pond netting. The netting can prevent many predators from snatching your fish out of the water. Not very aesthetic, but effective.

Pesticides and other contaminants may pose a hazard in an outdoor environment. Toxins can be washed into a pond during heavy downpours or may be blown into the water.  The rish is small as long as you stay aware when applying such products…something to keep in mind. Even the rain itself can be a danger to your fish. Acidic rain can drive your ph to low levels if you have a low kh. Depending on the species you’re keeping, such fluctuations can wipe fish out quickly.  I was able to keep the kh high and the ph stable with weekly buffered water changes so thi swas never a problem in my experiences.

Closing Time

Cool temps are the other concern. It’s important to know when to bring them in. For me, when night temperatures start dipping below 75 F, I know it’s time to bring them back to the tank. You may notice the fish becoming lethargic, and some may even die if you don’t pay close attention at the end of summer. I recommend acclimating them slowly back to indoor temperatures. If the filter running the pond is a canister filter, I would recommend keeping it running on the main tank. Clean it out before bringing it inside, but you’ll be supplying an established filter/biological for your indoor tank, and you don’t have to wait for the whole cycling process. We drain the pond each year and look for babies. You can then either store it till the following year or couple of set it back up in the house for the winter.

I hope this inspires someone else to try some tropicals outside. You wont regret it. Let me know if you have any questions, I’ll be happy to help you out.

Until next time,

Grading Scale

Below, we will go into the the types of aquarium filters and highlight some of the main points about each type.  We will grade each type on 6 factors independently.

Ease of Installation – Let’s face it – some filters can be a pain to install. Some of the more complex versions may require purchasing a drilled aquarium or a separate pump to sustain it.

Cost – Cost includes not only the price to purchase the filter, but the cost associated with installing it on your tank.

Upkeep – Some filters are basically set it and forget it – others require additional expense or maintenance along the way.

Space Requirements – Not everyone has room for a big filter in their setup. This category ranks not only how easy it is to fit under or on your aquarium, but also inside. I don’t know about you, but I don’t like to stare at aquarium equipment when I’m trying to check out my Tropheus

Biological Effectiveness – How well do these filters maintain effective biological filtration? Biological filtration is the most important aspect of aquarium filtration so this matters a great deal.

Chemical Effectiveness – Does the filter offer a level of chemical filtration – and how good is it?

Mechanical Effectiveness – Does the filter offer a level of mechanical filtration – and how good is it?

Noise – Noise can be a real concern for some aquarists and some filters are definitely louder than others.

Sponge Aquarium Filters

A sponge filter is one of the simplest aquarium filters available. They rate high for ease of installation, but are pretty limited in their effectiveness in all areas of aquarium filtration. They work with aquarium air pumps too – so you’ll have to purchase one of those. Most aquarists use them exclusively as add-on filtration or in small tanks like quarantine setups or transport tanks. They’re basically bacterial beds – their ability to filter mechanically and chemically is, for the most part, non-existent on most models.

Ease of Installation – Easy

Cost – Low

Upkeep – Low to Medium

Space Requirements – Low

Biological Effectiveness – Medium

Chemical Effectiveness – Low to Medium

Mechanical Effectiveness – Low to Medium

Noise – Medium

Undergravel Aquarium Filters

Undergravel Filters are a tried and true way of providing aquarium filtration to most size aquariums. They work by providing a gap between substrate and aquarium where beneficial bacteria can grow and thrive – providing consistent biological filtration to your tank. They are controversial however due to the risks associated with large scale biological breakdown underneath the plates. They also require the use of an aquarium air pump or powerhead to keep things flowing correctly and oxygen moving. They’re also pretty much a pain in the neck if you try to install them in an already-established aquarium due to the fact that you have to actually remove the gravel before installation. Given their limited filtration options, most aquarists tend to use them in conjunction with a power filter, canister filter or internal filter to supplement their biological filtration.

Ease of Installation – Easy

Cost – Low to Medium

Upkeep – Low to Medium

Space Requirements – Low

Biological Effectiveness – High

Chemical Effectiveness – Low to Medium

Mechanical Effectiveness – Low

Noise – Medium

Internal Aquarium Filters

Also called ‘In-Tank Filters’, these filters typically feature a motor to go along with fairly basic mechanical, biological and chemical filtration options. A favorite of tanks with low water levels and terrariums, these filters can be placed directly inside your tank and offer a higher level of 3-stage filtration than most of the options above. Aesthetically, they don’t blend in the way an Undergravel Filter does, but they still typically have a lower profile in your setup.

Ease of Installation – Easy

Cost – Low to Medium

Upkeep – Medium

Space Requirements – Medium

Biological Effectiveness – Medium

Chemical Effectiveness – Medium

Mechanical Effectiveness – Medium

Noise – Low to Medium

Power Filters

If there is a ‘traditional’ aquarium filter, the power filter would be it. Brands like Tetra’s Whisper, Marineland’s Penguin & Emperor, & Hagen’s Aquaclear have become household names in the aquarium industry due the ease, convenience and effectiveness of the power filter. A simple, magnetic impeller design combined with easy-to-replace filter cartridges make power filters a very effective for their price and simplicity. A simple hang-on-the-tank profile makes them easy to hide while still providing adequate 3-stage filtration for small to medium-size aquariums.

Ease of Installation – Easy

Cost – Low to Medium

Upkeep – Low to Medium

Space Requirements – Medium

Biological Effectiveness – Medium

Chemical Effectiveness – Medium

Mechanical Effectiveness – Medium to High

Noise – Low to Medium

Canister Filters

Canister Filters are great for providing a higher level of biological, chemical and mechanical filtration when compared to their power filter counterparts. Larger media areas and more stationary designs let you maintain larger bioloads and to maintain larger tanks in general. They’re also really easy to customize if you’d like to add additional filter media, while their specialized designs ensure a great water-to-media contact ratio so you maximize filter media effectiveness. However, what canister filters add in filtration capacity, they give back a bit in ease of installation, cost and space requirements. These big boys tend to cost a bit more and take up a bit more space under or behind your aquarium. They’re not always a walk in the part to install either.

Ease of Installation – Intermediate

Cost – Medium to High

Upkeep – Medium

Space Requirements – Medium

Biological Effectiveness – Medium

Chemical Effectiveness – Medium to High

Mechanical Effectiveness – High

Noise – Low

Wet/Dry Filters

Wet/Dry Filters are the pinnacle of aquarium filtration effectiveness. Most large scale aquariums employ some variation of wet/dry filtration in conjunction with an external sump system to maintain crystal clear, biologically sound environments in both fresh or saltwater. Their higher ratings for chemical and mechanical filtration are derived from the idea that, given that it’s a large, external sump, you can quickly and easily add large amounts of filtration pad or chemical media to facilitate your tank’s clean-up, but water contact is not ensured the way it is in a canister filter. But these filters are not for the timid. Large wet/dry sumps take up a lot of space. You also may need additional equipment or tank modifications to get yours to work correctly. Make no mistake, wet/dry filtration is the gold standard for biological aquarium filtration, but be prepared for a more complex installation, a higher starter cost, and greater space requirements than the other filters on this list.

Ease of Installation – Intermediate to Hard

Cost – High

Upkeep – Medium

Space Requirements – High

Biological Effectiveness – High

Chemical Effectiveness – Medium to High

Mechanical Effectiveness – Medium to High

Noise – Medium to High
