Abundant along shores and may be restricted to very small pools during summer. Feeds predominantly on terrestrial insects, benthic invertebrates and algae. Breeds in shallow riffle habitats, with strong current and stone or pebble bottom, at 10-20 cm water depth. Moves downstream in winter to deeper pools and to uppermost stretches of streams in summer .

🥚 Reproduction

Incubation
3days

Spawns in shallow riffles, with strong current and stone or pebble bottom, at 10-20 cm water depth. Females deposit eggs in 2-3 portions throughout the spawning period. Eggs are 1.9 in diameter, orange, adhere to pebbles and hatch in 3 days. Larvae do not possess adhesive glands, are negatively phototactic and hide under stones. They drift to shallow areas after active feeding activity commences .
