Description

The spot-tail robber is a slender, silvery characin of the family Alestidae (African tetras) reaching about 20 cm. The streamlined body has an adipose fin, as in many characins, and a conspicuous black spot on the tail base that continues as streaks into the tail lobes. The species comes from the fresh water of eastern and southern Africa and lives in schools in rivers, lakes and floodplains. As an omnivore it eats insects, zooplankton, seeds and plant matter, taken both 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 food fish in the region.
