Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 30.0 cm SL male/unsexed; (Ref. 43281)
soft rays: 74 - 84;
Vertebrae: 54 - 55. Head width 10.0-10.7% SL; caudal peduncle depth 4.3-5.1% SL; 74-80 anal fin rays, and 54-55 vertebrae (Ref. 52514). Dorsal fin much shorter than head length; maxillary barbel extending to middle of anal fin; mandibular barbels shorter than head; a small distinct spot at caudal-fin base; vomerine tooth patches joined at midline by narrow strip of teeth (Ref. 12693). Elongated dark blotch above pectoral base; sometimes a mid-lateral stripe on body; pointed caudal lobes (Ref. 43281).
Lives in lowland rivers and streams including peats (Ref. 57235). Occurs in medium to large-sized rivers (Ref. 12975). Found in slowly moving waters and lakes. Feeds on fishes, prawns, and crustaceans. Moves into seasonally flooded habitats during periods of high water and can usually be found around submerged woody vegetation. Marketed fresh (Ref. 12693).
