Maturity: Lm 45.5, range 50 - 60 cm
Max length : 125 cm TL 雄鱼/尚未辨别雌雄; (Ref. 36722); 最大体重: 2.9 kg (Ref. 40637)
Facultative air-breathing (Ref. 126274); Inhabit backwaters and slow moving sections of rivers and lakes. Often found in the warm stagnant waters of the lowland. Visible on the surface and resemble floating logs. Enter shallow lakes at the beginning of the dry season to spawn and known to reproduce also in June and July when rains are heaviest and rivers flood their banks providing an ideal spawning habitat of flooded vegetation. Large schools form to cast thousands of eggs in a gelatinous mass in the shallow waters. The adults return again to the river leaving the fry amongst the flooded vegetation (Ref. 36880). The eggs are poisonous to eat (Ref. 4537).
栖息于河川与湖泊的洄水区与缓慢移动的部分。 时常发现于低地的温暖污浊水域。 看得见的在表面上而且与漂浮的圆木相似。 在乾季的起点进入浅的湖泊产卵而且知道在六月与七月也繁殖当雨是丰沛的，而且河泛滥越堤提供一个茂盛的植物理想产卵的栖地的时候。 大的鱼群在浅水域中产下数以千计凝胶团状的卵。 成鱼再一次回到河里离开在茂盛的植物中的鱼苗。 (参考文献 36880) 卵是有毒。 (参考文献 4537)
