Description

Brycinus opisthotaenia is an African characin of the family Alestidae from the Congo basin in Central Africa. The species has a streamlined, laterally compressed, silvery body, often with a dark stripe toward the tail, and reaches about 13 cm. It lives in schools in the open water column of rivers and creeks and feeds as an omnivore on small invertebrates, insects and plant matter. Owing to its small size the species is mainly an important prey for larger fishes. Like many African alestids it is a fast, active swimmer in clear, flowing water.
