Duri punggung (Keseluruhan (total)) : 2; duri punggung lunak (Keseluruhan (total)) : 7; Duri dubur: 0; Sirip dubur lunak: 29 - 32. Eye small, its diameter more than 7 times in head length (in 18 cm long specimens); bright yellow caudal fin in adults; maxillary barbel extends to gill aperture; 23-28 gill rakers on first arch (Ref. 12693).
Facultative air-breathing (Ref. 126274); Found in large rivers and estuaries (Ref. 4833). Occurs in high estuary (freshwater tidal zone) as juveniles, moving to brackish water as sub-adults, and finally as adults to river mouths and inshore areas (Ref. 12693). Longevity given as 10 years (Ref. 2686) but appears too low. Feeds on snails, other mollusks (Ref. 1479) and plants (Ref. 4833). Reared for consumption in Thailand, Cambodia and Vietnam; excellent food fish with very white fine grained sweet flesh (Ref 2686). Marketed fresh (Ref. 12693).
