The Sawfin is omnivorous, but mainly eats aquatic insects and their larvae.
The Sawfin (Barbus serra), also known as Clanwilliam Sawfin, is a ray-finned fish species in the family Cyprinidae. It is endemic to the Western Cape Province of South Africa, where it was formerly widespread in the Olifants River and its tributaries. Its range has decreased throughout most of the 20th century, and by now it is apparently only found in the upper Olifants River as well as the Biedou, Doring, Driehoeks, Jan Dissels, Oorlogskloof, Ratels and Tra Tra Rivers.
