Found in large rivers, lakes and tanks. A large, voracious and predatory catfish which thrives in heels with grassy margin (Ref. 6028); mostly hides under holes in river banks and canals (Ref. 44149). Associated with deep, still or slow-flowing water with a mud or silt substrate (Ref. 6028). Sluggish and stays on muddy or silty bottom in search of food. Juveniles feed mainly on insects; adults feed on smaller fish, crustaceans, and mollusks. Oviparous, distinct pairing possibly like other members of the same family (Ref. 205). Abundant during the warm season; a pre-monsoon summer breeder. In the Mekong, it is reported to migrate to smaller streams, canals and to the floodplain during the flood season (Ref. 37770). When the water level in the Mekong drops and the flood recedes, it moves to the Mekong or larger tributaries, where it stays in deep pools until the next inundation period (Ref. 37770). Destructive to other more valuable food-fishes. Bites strongly if handled, with its huge mouth, formidable jaws, and band of conical teeth. Threatened due to over harvesting (Ref. 58490).
發現於大河，湖與水族箱.。 在具有長滿草的邊緣的底部中繁榮的一個大的﹐狼吞虎嚥的與掠食性的鯰魚;(參考文獻 6028) 大部份在河岸與管中藏在洞下。 (參考文獻 44149) 深地伴隨著., 靜止或流動很慢水具有一個泥或淤泥底部。 (參考文獻 6028) 緩動性的與在泥濘或淤泥的底部以找尋食物上的停留。 稚魚主要捕食昆蟲; 成魚吃較小的魚，甲殼動物與軟體動物。 卵生的, 明顯的成對可能地像其他的相同該科的成員.(參考文獻 205) 豐富的在溫暖的季節期間; 一個前季風夏天養育者。 在湄公河中，它被報告在洪水季節的時候迴游到較小的溪流，管與到洪泛區。 (參考文獻 37770) 當湄公河下降與洪水的水位後退的時候，它移動到湄公河或者較大的支流, 在那裡它停留在深水池中直到下一個淹水時期.(參考文獻 37770) 對其他的比較有價值的食用魚的破壞力。 強烈地咬如果觸摸, 用它的極大嘴，強大的顎與錐形齒箍。 受威脅的捕穫之上由於.(參考文獻 58490)
