Hypselobarbus

Jerdon's carp, Hypselobarbus jerdoni, is a large cyprinid endemic to India, recorded from Maharashtra, Karnataka, Kerala and Tamil Nadu. A riverine fish of clear, well-oxygenated, running water, it can reach 46 cm and is very rarely encountered in the trade. Very active and a vigorous feeder, it needs a tank of 240 ∗ 120 ∗ 120 cm or more for a group of adults, and many Indian authors consider it endangered.
