Mouth very small, very oblique, upper jaw vertical and somewhat protractile, lower jaw prominent. Scales of moderate size, irregularly arranged. Lateral line curved, irregular. Caudal fin slightly emarginate or truncate (Ref. 4792). With 8-9 dorsal-fin branched rays; 33-38 branched anal-fin rays; black spot in middle of side and at caudal-fin base (Ref. 12693).

Asia: Mekong basin in Laos, Yunnan, Thailand, Cambodia and Viet Nam; Southeast Asia (Ref. 27732). Introduced elsewhere (Ref. 2847).
Lives in lowland wetlands (Ref. 57235). Found in marshes, swamps and canals (Ref. 43281). Inhabits shallow sluggish or standing-water with a lot of aquatic vegetation. Occurs in seasonally flooded forests throughout the middle and lower Mekong (Ref. 12693). Undertakes lateral migrations from the Mekong mainstream, or other permanent water bodies, to flooded areas during the flood season and returns to the permanent water bodies at the onset of the dry season (Ref. 37770). Feeds on zooplankton, crustaceans and insect larvae. Processed into salted, dried fish in Java (Ref. 4929). Also marketed fresh and commonly seen in the aquarium fish trade (Ref. 12693). Aquarium keeping: minimum aquarium size 100 cm (Ref. 51539).

Bayesian length-weight: a=0.03160 (0.01501 - 0.06654), b=3.05 (2.85 - 3.25), based on LWR estimates for species & Subfamily-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 2.7 ±0.23 se; Based on food items.
Resilience (Ref. 69278
