Adults inhabit hill streams up to an elevation of 300 m (Ref. 4832). Found in shaded, mid-hill clear waters with pebble or gravel substrates (Ref. 11966). They occur in schools at the surface in small high-gradient upland streams (Ref. 12693). They feed mainly on exogenous insects (Ref. 12693) and also on worms and crustaceans (Ref. 7020). Not seen in markets, but popular in aquarium trade (Ref. 12693, 44325). Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 100 cm (Ref. 51539).
