Short description

Dorsal spines (total): 3; Dorsal soft rays (total): 8 - 10; Anal spines: 3; Anal soft rays: 9 - 11; Vertebrae: 47 - 48. Caudal fin with 19 to 21 rays (Ref. 40476).

Gregarious. Occurs in fairly shallow water with fast current, often beside the swirls created by piles of bridges or rocks (Ref. 30578). Found in the upper reaches of rivers. Feeds on algal growth on stones, which are scraped away with the use of its sharp, low, slit-like mouth (Ref. 9696). Migrates upstream and enters small tributaries for spawning in shallow water on gravel (Ref. 556). Its flesh is good but bony (Ref. 30578).
