Adults occur in still waters of streams and swamps where it is usually seen near the surface or close to shore among aquatic vegetation (Ref. 2847, 44894). Solitary, territorial and spawn prior to the wet season when surface water temperatures approach 30°C (Ref. 44894). Young feed primarily on microcrustaceans (Ref. 2847). Primarily a surface feeder, feeding on a variety of terrestrial and aquatic insects, small fishes, frogs, crustaceans, and some plant material (Ref. 44894). Mouthbrooders (Ref. 56180). Maximum weight reported in Ref. 5259 may be 12.27 kg (W. Lau, pers. Comm. 07/05). Important food fish (Ref. 58511) and a valuable aquarium fish (Ref. 83518).
成魚出現在溪流與沼澤的靜止的水域在那裡它通常是見到接近水表面或者接近在水生植物之中的海岸.(參考文獻 2847,44894) 獨居性, 領域性而且在地表水溫度接近 30 °C 的濕季之前產卵.(參考文獻 44894) 幼魚主要捕食小型甲殼類動物。 (參考文獻 2847) 主要地一個水面捕食者, 吃多種陸生與水生昆蟲，小魚，青蛙，甲殼動物與一些植物。 (參考文獻 44894) 口孵魚.(參考文獻 56180) 最大的重量參考文獻 5259 報告可能是 12.27 公斤 (W. Lau ， pers. Comm。 07/05). 重要的食用魚.(參考文獻 58511)
Fertilized eggs are carried in the mouth of the female. Eggs hatch in 1-2 weeks. Larvae, with their enlarged yolk sac, are kept in or close to the mouth for another 4 or 5 weeks. Young fish commence feeding, primarily on microcrustaceans, at a size of 2-3 cm, well before the yolk sac is entirely resorbed. Become independent at a length of 3.5-4.0 cm.亞洲與大洋洲: 澳洲北部與中央-南方的新幾內亞.(參考文獻 58511)
