Description

The smallmouth African tetra is a slender, silvery characin of the family Alestidae (African tetras) reaching about 17 cm. The laterally compressed body has, unlike many relatives, a notably small mouth and bears an adipose fin (as in many characins); the male develops an enlarged, taller dorsal fin in the breeding season. The species comes from the Congo basin in Central Africa and lives in schools in rivers, creeks and floodplains. As an omnivore it eats insects, seeds, plant matter and zooplankton, taken at the surface and in the water column. In the rainy season it spawns on flooded margins. Through its great numbers it is an important prey fish and a much-caught small food fish.
