Occurs from near sea level to nearly 1,520 m (Ref. 2801). Prefers deep pools and slow-flowing river stretches but does occur in rocky rapids. Feeds on green algae, diatoms and detritus. Shoals migrate upstream in spring and summer to breed. Large numbers of small eggs are laid and young are found in shallow backwaters. Could be exploited from dams (Ref. 7248).
