Description

The true big-scale tetra is a deep, silvery characin of the family Alestidae (African tetras) reaching about 53 cm. The laterally compressed body has conspicuously large, shiny scales, an adipose fin (as in many characins) and bears a dark spot on the tail base and on the dorsal fin. The species comes from much of West and Central Africa and lives in schools in rivers, lakes 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. With its size and tasty flesh it is an important commercial and sport fish in the region.
