Occurs in a variety of habitats: quiet well vegetated backwaters, standing open waters, flowing open waters, sandy-rocky stretches and rocky rapids. Their preferred habitat is flowing rocky channels. Bottom feeder which grazes algae and organic detritus (Ref. 6465). Breeds in summer, gathering in large numbers in shallow rocky rapids where eggs are laid. Larvae hatch after 3 or 4 days.
