Frequently occurs in counter current zones of principal rivers and creeks. Feeds mainly on fish but also on other animals that fall into the water like small terrestrial invertebrates. Is active at dusk and at night. Reproduction takes place at the onset of the rainy season from December to March. Depending on the size, the female can carry around 6,000 to 60,000 eggs (Ref. 12225). Known for the quality of its flesh (Ref. 27188).
時常出現於主要河與小溪的逆流區中。 主要吃魚也捕食其他的掉入水中相似的小陸棲的無脊椎動物的動物。 在薄暮是活躍的而在夜晚。 繁殖發生在雨季的開始從十二月到三月。 依據大小而定, 母魚能運送大約 6,000 到 60,000個卵。 (參考文獻 12225) 以它的肉的品質聞名。 (參考文獻 27188)
