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).
出現於大多數的棲息地類型，但是大部分常見於大的泥濘河中, 且水流和緩的地方與軟質底部的.(參考文獻 27732) 進入被水淹沒的森林。 (參考文獻 9497) 吃外生的昆蟲，水生的昆蟲幼生，蝦，其他的甲殼動物和魚類。 移入被水淹沒的森林產卵，而且幼魚是在通常第一個中見到的八月。 在 Tonle Sap(柬埔寨) 中，當它在十一月與十二月回到河的時候，最大的數字被發現。 一個價格很高的水族館魚。 通常生鮮地在市場上銷售。 (參考文獻 12693) 高度地在有營養的價值中尤其亞米茄-3 脂肪酸 (環保署, 二十二碳六烯酸).(參考文獻 53337)
