Comments: Known from the Mekong basin. Found in the middle Xe Bangfai (Ref. 27732) and Ban Hang Khone at Don Khone, 3 km below the fall line of the great waterfalls of the Mekong basin at Lee Pee (Ref. 9497). Occurs during dry season in deep slow reaches of the Mekong basin at Muang Khong (Ref. 37769). Migrates upstream in December-March and appears to engage in two separate types of migration at Hat Village, Muang Khong: the first an upstream reproductive migration arriving in the Muang Khong area in late December and early January and the second, a post-spawning movement which may have a trophic component (Ref. 37769). Observed to undergo migration and fished heavily at the fishing village of Ban Wernsonkhram on Don Hat (Hat Island) above the Lee Pee Waterfalls (Ref. 10431). Also Ref. 4792, 30857, 36654, 37767, 56905.

Short description Morphology | Morphometrics

Branched dorsal rays 13-15; branched anal rays 6; narrow mouth with narrow and slender jaw (width 8-10% in head length); fleshy lower lips; pale orange caudal fin in life.

Occurs in large river habitats (Ref. 12693). Inhabits deep slow reaches during dry season (Ref. 37769). Found in rapid-running mountain streams (Ref. 12975). Not known to migrate, but may probably leave main stream for flooded forests during the periods of high-water. Has not been found in any impoundments. Omnivorous, feeding on detritus and algae along with worms, crustaceans and insects. Marketed fresh (Ref. 12693).
