Short description

Vertebrae: 40 - 45. Pelvic-fin origin usually behind the base of the last dorsal ray; adipose-fin origin in front or above the anal-fin origin (Ref. 27732). Elongate neural spines 2-5, slender; abdominal vertebrae 21-24 (Ref. 35669). Eye circular, diameter 10-13 times in HL; head width 4.3-4.7 times in SL (Ref. 43281).

Occurs in large rivers on the bottom, even with swift current (Ref. 12693). Never enters small streams (Ref. 37770). Found among boulders, often in the white water of the rapids where it apparently is indifferent to the strong current. Feeds primarily on prawns but will take small fishes and aquatic insects (Ref. 6868). Spawns in rivers before the rainy season (Ref. 12693). Migrates in schools. Reported to migrate to follow its prey. Also reported that it follows Catlocarpio siamensis during its upstream migration (Ref. 37770). Apparently the main upstream migration begins close to the peak of flood when the current is very strong and the water is turbid (Ref. 37770). Sold fresh in markets. Not a highly esteemed food fish, because its fibrous flesh spoils rapidly and can cause illness (Ref. 12693).
