Mainly riverine species, but also occurs in lakes near river mouths and in vegetated fringes and in swamps (Ref. 80296). Also found in rapids where it hides among rocks (Ref. 85214). Essentially a sedentary fish, nocturnal and usually waiting for its prey to swim or drift within range whereupon fish will dart out of its shelter to seize it (Ref. 89002). Feeds on aquatic insect larvae (Ref. 80296), lithophilic insects (Ref. 12526), fish (Ref. 13624, 27292), shrimps (Ref. 246, 80296), oligochetes and occasionally vegetable matter (Ref. 80296, 89002). Breeds during flood season, in inundated areas (Ref. 80296). Eggs yellow and large, probably spawned among water weeds (Ref. 89002).
出现于沼泽与沿岸浅水区。 (参考文献 6060) 吃鱼与昆虫。 (参考文献 13624)
