The curious-looking African Butterfly Fish originates from the calm waters of creeks, swamps and slow-moving parts of rivers, where they inhabit the area just underneath the water's surface. They are excellent jumpers, so the aquarium MUST have tight fitting coverslides to prevent accidental escape. In the wild, the African Butterfly Fish feeds on small fish, crustaceans, aquatic larvae & nymphs, as well as terrestrial insects (hence it's position in the water column and its ability to jump).
