Biology

Occurs in fast flowing, clear waters with stony substrate (Ref. 27732). Found in clear mountain streams usually under complete forest canopy (Ref. 12693). Encountered in rapid-running mountain streams of the middle Mekong (Ref. 12975). Feeds mainly on insect larvae along with small amounts of detritus and periphyton. Apparently breeds after the end of the rainy season after water levels in upland areas have declined, and juveniles appear in catches during April. Not seen in markets (Ref. 12693).
