Fin-tastic Freshwater Butterflyfish Facts For Kids

Discover interesting freshwater butterflyfish facts.

The freshwater butterfly fish (Pantodon buchholzi) is also known as the African butterflyfish. These are native to Africa occupying a wide range of water bodies. This fish species belongs to the order Osteglossiformes and the family Pantodontidae.  This species of fish is usually confused with saltwater butterflyfish, but they are not closely related. The freshwater butterfly fish is the only member of this family. They are carnivorous and always capture prey at the surface. This fish is widely distributed across large water bodies in West Africa. They can jump and glide for a short period above the water's surface to escape predators. Due to this ability, they were named freshwater butterflyfish. This species is quick and agile, making them top predators. Even though this species has been around for a long time, they were officially approved in 1905. They have survived all kinds of environmental changes without any modification or effect on distribution to date. They are also referred to as living fossils. They also do well alone and in a community tank with appropriate conditions. Arowanas and bony-tongue fishes are distant relatives of freshwater butterflyfish.

Freshwater Butterflyfish Interesting Facts

What type of animal is a freshwater butterflyfish?

The African butterflyfish (pantodon buchholzi) is also called a dragon fish and is a trained surface feeder. They can also breathe in air like us.  It is their vasculature swim bladder that administers buoyancy and exchange of gas while they are on the surface of the water. They feed on anything with high protein. This freshwater fish does not do well with their own kind in an aquarium. They also do not move around a lot and they stay in the same place near the surface to catch prey. They can sometimes be aggressive.

What class of animal does a freshwater butterflyfish belong to?

Freshwater butterfly fish (Pantodon buchholzi) belong to the Actinopterygii class of animals.

How many freshwater butterflyfish are there in the world?

This freshwater fish species are mainly found in large water bodies and their number is increasing. There is no data available on the exact number of these fish.

Where does a freshwater butterflyfish live?

The African butterfly fish (pantodon buchholzi) is found mainly in West African water bodies. They live in Nigeria, Cameroon, and Zaire. They are found in the lower Niger, Lake Chad, Congo Basin, upper Zambezi, and Ogooue. This fish also inhabits the lower Cross River and the Niger Delta.

What is a freshwater butterflyfish's habitat?

The distribution of this African butterfly fish is across water bodies with slightly acidic and slow water movement. The habitat of these fish include a high amount of foliage that floats to the surface of the water. They also occupy creeks, lakes, and swaps with floating plants. The water temperature is 73-86 F (23 30 C). Freshwater butterflyfish are found in areas with submerged and overhanging vegetation. These fish can camouflage well in these regions.

Who do freshwater butterflyfish live with?

The African butterfly fish live both on their own and in pairs.

How long does a freshwater butterflyfish live?

The African butterfly fish's lifespan is five years. They can also live longer in an aquarium with proper conditions and nutrition.

How do they reproduce?

It is quite a task to breed this fish species in captivity. It is necessary to move the breeding pair into a separate fish tank and it is hard to distinguish females from males. They require an adequate tank size with floating plants, a big surface area, and good water conditions. After setting up the natural habitat, make sure that the water temperature is 80 F (27 C). A little bit of water has to be removed to start the breeding process. High-quality food should be fed to the breeding pair like brine shrimp, flake food, crickets, small fish, and insects. The tanks have to be left in these conditions for few days before adding acidic water. Males usually chase females. The spawning takes place within the plants, and the male clasps the female with his fins. After the pair starts the breeding process, the female produces three to seven eggs per pass. By the end of the breeding season, the female produces about 200 eggs per day. The fertilization of eggs takes place internally. Females scatter the eggs in the water body. The eggs float to the surface, and they have to be separated and kept in different tanks. If the eggs are in the same tank, the parents might eat them. The fry hatches in four days. The fry does not hunt as they usually wait on the surface of the water. It is difficult to raise a juvenile and they can be fed food like young brine shrimp. The water needs to be changed regularly.

What is their conservation status?

The African butterflyfish (pantodon buchholzi) fish species are listed as Least Concern. Due to the modern-day breeding of them in captivity, their distribution in the wild has not been affected.

Freshwater Butterflyfish Fun Facts

What do freshwater butterflyfish look like?

The African butterfly fish is about 5 in (13 cm) long with large pectoral fins. They have a vascularized and large swim bladder. This swim bladder enables them to breathe air at the surface of the water. They have well-trained eyes and upturned mouths to catch prey near the surface of the water. They use their enlarged pectoral muscle to glide on the surface of the water. When looked at from the top, their pectoral fins resemble the wings of a butterfly. This fin also makes them look like floating plants. The fish has a brown and black patterned body and light-colored underbelly. This fish has orange-colored eyes placed higher up on their head. Males are slimmer than females, and the anal fin is different. The reproductive organ on the rear edge of the anal fins is a small tube formed by fin rays. The anal fins of the female fish have a straight edge. The caudal fin is larger than the dorsal and anal fin. The caudal and anal fin helps the fish to propel forward. These fins have dark even-spaced lines. The ventral fin resembles a thin barbel.

The African butterfly fish have simultaneous water and air vision

Would they make a good pet?

With proper aquarium and tank size, this fish can be a good pet. Feeding them nutritious food like small fish, freeze-dried food, insects like crickets, and providing them with their natural habitat in the tanks will keep them healthy. Many professionals suggest that only experienced aquarists can handle them. They can be fussy about the tank size, habitat, or their care. The aquarium must have a filter with a low water current.  A small amount of water must be changed frequently to maintain the required water conditions. To provide proper care, they must be in a tank size of 30-40 gal (136-182 l), the water must have a pH level of 6.5 to 7, and the water hardness should be at 1-10 KH. The flow of water should be slow.

Kidadl Advisory: All pets should only be bought from a reputable source. It is recommended that as a potential pet owner you carry out your own research prior to deciding on your pet of choice. Being a pet owner is very rewarding but it also involves commitment, time and money. Ensure that your pet choice complies with the legislation in your state and/or country. You must never take animals from the wild or disturb their habitat. Please check that the pet you are considering buying is not an endangered species, or listed on the CITES list, and has not been taken from the wild for the pet trade.

Did you know...

Pantodon (genus) is a Greek word with two elements, 'pan' meaning 'all' and 'odon', meaning  'teeth', so it literally translates to 'all tooth'. Buchholzi is the surname of the man who discovered the butterflyfish, Professor R. W. Buchholz.

As the butterfly fry starts to grow, it was observed that they show cannibalistic characteristics. The larger fry will eat their smaller siblings.

The African butterflyfish migrates to other freshwater regions.

The lids of aquariums or tanks must be tight-fitting because butterflyfish are good jumpers.

The African butterflyfish does not do well in places with cold air.

When in danger, African butterfly fish use their fins as ailerons to launch themselves from the water, rising about twice their body length

It is observed that African butterflyfish remain a lot calmer in a dark substrate.

Can angelfish live with butterflyfish?

No. African butterfly fish and angelfish do not do well as tank mates. Angelfish are mainly bred in captivity as they are difficult to catch in the wild. This fish also finds food near the surface of the water. As tank mates, both these fish species would display aggressive behavior. Another reason is that angelfish are fin-nippers. The long flowing fins of butterflyfish are possibly targeted by these fin-nippers

There are other suitable tank mates for butterflyfish. Their usual behavior is peaceful if their territory is not disturbed. It is necessary to choose a tank mate for your fish, considering factors like tank size, temperament, water conditions, and fish size. It is best to keep them with similar-sized or small fish that are middle or bottom dwellers of an aquarium. Butterflyfish can be placed with barbs, gouramis, catfish, elephant fish, cories, danios, and tetas.

Why are butterflyfish called butterflyfish?

The silver brownish-green colored large pectoral fins with markings are what gave them this name. They are fan-like when viewed from the top and look like the wings of a butterfly. They are usually faced away from the surface so they are not detectable by a predator or prey.
