Description

The Congo eugnathichthys is a slender African characin of the family Distichodontidae reaching about 15 cm. The silvery, elongate body has an adipose fin and a few dark spots on the flank. The species comes from the Congo basin in Central Africa and lives in schools in clear, flowing rivers and creeks. Notable is its feeding behaviour: besides insects and small crustaceans it also nibbles pieces of the fins and scales of other fish, a form of fin- and scale-eating found in a few relatives. In the rainy season it spawns. Because of its small size and great numbers it is a link in the food web of the Congo rivers and a prey fish for larger species.
