Comments: This is a Premium Pet Fish, and we never see Premium Fish like this in any of the live fish stores that we visit.

Premium Pet Fish are more energetic, hardier, and have brighter colors with a beautiful metallic sheen.

Origin: This Wild Fish was caught in the Congo River Basin in Africa.

Maximum Size: This Fish is said to grow to be 15" long, but we've never seen one bigger than 8" long, including the tail.

Behaviors: They will usually move around pretty actively during the day, but some of them seem to hide during the day and become more active at night.

When there is food to be eaten, they become very active looking for it.

They'll also eat very small fish like Neons, Guppies, and other fish small enough fit into their mouths.

Compatibility: Some recommended tank mates include any fish that are not too aggressive toward them. They can also eat smaller fish so be careful when choosing tankmates.

Temperature: They live well from about 78 to 82 degrees F., but they're probably most comfortable at about 78 degrees F.

Feeding: They need to eat worms and frozen brine shrimp and bloodworms. Sometimes they'll eat premium pellet food.

Water Conditions: This Wild Fish seems to be tolerant of a wide range of water conditions. Probably a pH of about 6.5 with moderate hardness is best.

Most water in the US seems to be OK, so it's probably best NOT to adjust the pH or the hardness of the water.

Here in our facilities the water is hard and the pH is usually about 7.8. We ship them in this water.

Aquarium Size: It's probably best to house these fish in at least a 50-gallon tank, but bigger is better. Eventually one Baby Dolphin will need an aquarium with at least 100-gallons of water.

Decor: They don't need gravel, and a layer of gravel more than 1/4" thick will usually fill with bits of uneaten food that will contaminate the water.

Live Plants are beautiful and improve the water quality, they are also necessary if planning to spawn these fish. They use the plants for camoflauge as well.

Aquarium Filter: Bio-Wheel Filters are highly recommended. A Penguin 350B Filter in an aquarium with 50-gallons of water is OK to start.

But eventually this fish will need at least a 100-gallon aquarium with several Penguin 350B Filters or a large filtering system.

The addition of aquarium-safe Lava Rocks will keep nitrates in the ideal range. Click here to learn more about using Lava Rocks in aquariums.

Life Span: These Wild Fish can live for several years, probably many years provided they are fed properly and kept in a very large aquarium with very fresh water.

Gender: It is very difficult to determine the gender of these fish, the female may become plumper when ready to breed.

Breeding: There are no known reports of successful breeding in captivity.

Popularity: This Wild Fish is somewhat popular but rare ... very rare.

Names: The scientific name is Gnathonemus rhynchophorus.

Variations: This Wild Fish lives across a wide range in the Congo basin in Africa, so there may be variations, but we haven't seen any.
