reedfish
The reedfish, ropefish (more commonly used in the United States), or snakefish, ''Erpetoichthys calabaricus'', is a species of freshwater fish in the bichir family and order. It is the only member of the genus ''Erpetoichthys''. It is native to West and Middle Africa, with its natural habitat stretching from the Ogun River (Nigeria) to the Chiloango River (Republic of the Congo).
The reedfish has a maximum total length of . It lives in slow-moving or standing, brackish or fresh, warm () water.〔 It can breathe atmospheric air (meaning it is able to survive in water with low dissolved oxygen content) using a pair of lungs. This organ means it can survive for an intermediate amount of time out of water.〔 The reedfish is nocturnal, and feeds on annelid worms, crustaceans, and insects.〔 It is sometimes displayed in aquaria. Its genus name derives from the Greek words ''erpeton'' (creeping thing) and ''ichthys'' (fish). The genus is also known by the name ''Calamoichthys''.〔L. Fishelson, Zoology, renewed and corrected ed. 1984, Hakibutz Hameuchad Pub. House, Israel 1984. Vol II, p.126 (Hebrew)〕
==In the aquarium==
Reedfish are inquisitive, peaceful, and have some "personality". Since they have a peaceful nature, other fish may 'bully' a reedfish, despite its large size, especially in competition for food or space. They have been known to jump out of aquariums and slither around, because they have lungs along with their gills. Although nocturnal, reedfish will sometimes come out during the day, and this can be encouraged by daytime feeding of bloodworms or nightcrawlers for larger fish. Some reedfish also have an inclination to stay close to the water surface, where they will be safe from other fish and will even allow most of their bodies to leave the water at times.
