DISTRIBUTION/HABITAT: Central Congo basin of Africa. Found in freshwater streams in schools of hundreds to thousands.

DIET IN THE WILD: Omnivorous scavenger: Feeds mainly at night on insects, crustaceans and filamentous algae, plant debris, bowels of dead fishes. Grazes algae from undersides of cave ceilings or leaves with its little rasp-like teeth while in the inverted position, a posture also used while gleaning food from the water’s surface. Also locates food on the substrate among debris such as rotting plants.
