Description

Brycinus bimaculatus is an African characin of the family Alestidae from eastern and Central Africa. The species has a streamlined, silvery body with usually two dark spots and reaches about 14 cm. It occurs in rivers and shoreline zones of lakes and lives in schools in the open water column. As an omnivore it feeds on sand-associated algae, plant debris, insects and small invertebrates; juveniles feed mainly on cladocerans. Owing to its abundance the species is an important prey for larger predatory fishes. It is of limited local fishery importance.
