Has the upper lip not separated from the snout by a rostral groove; no mental disc; no barbels; no rostral lobe; 10 branched dorsal rays.
Body shape (shape guide): fusiform / normal.
Found in rapidly flowing water in medium and large-sized rivers (Ref. 12693). Inhabits slower deeper reaches during dry-season (Ref. 37769). Prefers rocky stretches with rapids and a fast-flowing current (Ref. 37770). Feeds on aquatic chlorophytes (Ref. 37769 ), periphyton and phytoplankton (Ref. 12693). Migrates in big schools, comprising several hundred fish, usually together with other cyprinids and loaches such Hypsibarbus spp., Scaphognathops spp., Cirrhinus siamensis and Botia modesta (Ref. 37770). Sold fresh, sometimes dried or salted (Ref. 12693).
