Description

The onestripe barb is a slender, silvery African barb of the family Cyprinidae reaching about 14 cm. The body is silvery with a golden sheen and bears a conspicuous dark stripe along the flank that gives the species its name; fine barbels surround the mouth. The species lives in schools in streams, rivers and swamps with abundant water plants in West and Central Africa. As an omnivore it eats insects, small crustaceans, algae and detritus, taken in the water column and from the bottom. In the rainy season it spawns on flooded margins, where the young grow up quickly. Through its great numbers it is an important prey fish for larger species and waterbirds.
