Description

The hi-fin congo tetra is a slender, shiny African characin of the family Alestidae reaching about 7 cm. The laterally compressed body has large, shiny scales, an adipose fin (as in many characins) and an iridescent blue-yellow sheen on the flank; males often have somewhat extended fins. The species comes from the Congo basin in Central Africa and lives in schools in clear, flowing rivers and creeks. As an omnivore it eats insects, zooplankton, algae and plant matter, taken in the water column and at the surface. In the rainy season it spawns. Because of its handsome sheen it occasionally appears in the aquarium hobby, and in the wild it is a prey fish for larger species.
