Description

The African red-eyed tetra is an African characin of the family Alestidae from the Niger Delta and coastal lowlands of West Africa. The species grows to about 10 cm and has a streamlined, silvery body with large scales, a red mark above the eye and a dark blotch on the anal fin. It lives in schools in slow-flowing coastal waters and is an active swimmer. As an omnivore it feeds on worms, insects and crustaceans. In spawning the female lays up to a thousand eggs after vigorous courtship, which hatch within a few days. Owing to a restricted range and habitat pressure the species is listed as Endangered (EN). It is harmless to humans.
