Occurs in most habitat types, but most frequent in large muddy rivers, with slow current and soft bottom (Ref. 27732). Enters flooded forest (Ref. 9497). Feeds on exogenous insects, aquatic insect larvae, shrimps, other crustaceans and fishes. Moves into flooded forests to spawn and the young are usually first seen in August. In Tonlé Sap (Cambodia), maximum numbers are found as it returns to rivers in November and December. A highly priced aquarium fish. Usually marketed fresh (Ref. 12693). High in nutritive values especially omega-3 fatty acids (EPA, DHA) (Ref. 53337).
