Description

Distichodus rostratus is a large African fish of the family Distichodontidae from the Sahel region and West Africa. The species has a deep, laterally compressed, silvery to yellowish body with a pointed snout and fleshy lips, and can reach about 76 cm. It lives in rivers and is a markedly plant-eating species (macroherbivore): it grazes submerged water plants, the roots of water hyacinth and periphyton. Owing to its size and occurrence in large numbers the species is important for fisheries and a valued food fish. Juveniles are sometimes found in the aquarium trade for their handsome shape.
