Ptychobarbus is a genus of cyprinid fish that is found in rivers, streams and lakes in the Himalayas and Tibetan Plateau of China, India, Nepal and Pakistan, extending into the highlands of Afghanistan. They reach up to 2.2 kg (5 lb) in weight and about 65 cm (2.1 ft) in total length.[1] They mostly feed on benthic invertebrates, but will also take planktonic organisms, aquatic plants and algae.[2]
