Biology     Glossary (e.g. epibenthic)

Inhabits small streams, reservoirs, lakes (Ref. 4832), canals, ditches, and generally areas with slow moving or standing water (Ref. 12693). Occurs in medium to large-sized rivers (Ref. 12975, 57235). Stomach contents are composed of fish and insect remains (Ref. 56749). Typically found around surfaces, such as plant, leaves, branches and tree roots where it browses for small plankton and crustaceans. Moves into flooded forests and non-forested floodplains. Reported to breed late during high-water season from September to October as water levels peak and begin to decline (Ref. 12693). Found in the basin-wide tributary of the lower Mekong (Ref. 36667). Common foodfish in markets (Ref. 57235).
