Occurs mainly in heavily shaded streams and rivulets, preferring shallow, slow-flowing water with silt substrate and leaf debris. Omnivorous, the gut containing detritus, green algae, diatoms, dipterans and animal matter. About 200 eggs are scattered among marginal plants. Young hatch in 1-2 days and are free-swimming after 48 hours. Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 60 cm (Ref.
