|Current Population Trend:||Unknown|
|Habitat and Ecology:||Occurs in the fast-flowing clear waters of highland streams with stony substrates, usually under complete forest canopy. Encountered in rapid-running mountain streams of the middle Mekong basin. Feeds mainly on periphyton of rocky surfaces. Apparently breeds after the end of the rainy season after water levels in upland areas have declined, and juveniles appear in catches during April (Rainboth 1996).|
|Movement patterns:||Full Migrant|

|Major Threat(s):||Deforestation, overfishing and illegal fishing are potential threats to this fish, but no significant population decline has been shown recently.|
|Conservation Actions:||Some of this species' population occurs in protected or locally managed areas.|
