Description

The sharptooth tetra is a small, silvery African tetra of the family Alestidae (African tetras) reaching about 9 cm. The slender, laterally compressed body has an adipose fin, as in many characins, and a dark stripe on the tail base. The species is one of the most widespread small tetras of Africa and lives in large schools in rivers, lakes and floodplains. As an omnivore it eats insects, zooplankton, seeds and plant matter, taken in the water column and at the surface. In the rainy season it spawns on flooded margins. Through its great numbers it is an important prey fish for larger species and occasionally appears in the aquarium hobby.
