Feeds mainly on plant matter including fruits, leaves, and flowers, with some insects and crustaceans. Known to reproduce in non-flowing waters near the river shore during lowest water levels (Ref. 12693). Undertakes lateral migrations from the Mekong mainstream into floodplain areas during the flood season and returns to the Mekong River or other permanent water bodies during the dry season (Ref. 37770). These movements are triggered when water levels change (Ref. 37770). Marketed fresh (Ref. 12693). Rainboth, W.J. 1996 Fishes of the Cambodian Mekong.

In large specimens examined, over 40 cm SL, all of the jaw teeth are enlarged, especially those in the outermost rows, which lie on the external surface of the jaws entirely outside the mouth when it is shut. Coloration of juveniles and adults also is diagnostic. Small juveniles have 6 or 7 vertical bars and a supra-anal dark oval spot, none of which are retained by adults and subadults. Juveniles over about 10 cm have a reddish orangish stripe on the lower part of the head and breast, a feature not observed in any other species. All adults have extensive dark (almost black) areas ventrally and pale areas dorsally. Several large specimens (especially from Stung Treng market, Cambodia) with large and irregular red blotches that superficially at least look very muck like bodied bruises.
