Opercular ocellus present.
鳃盖眼状斑呈现。
Obligate air-breathing (Ref. 126274); Inhabits swamps and creeks with little current (Ref. 12225), as well as in flooded savannas (Ref. 27188). Regularly goes to the surface of the water to breathe. Can survive long periods out of the water. This behavior of breathing air at the surface makes the fish vulnerable to predation by electric eels (Ref. 27188). Is a predaceous omnivore of open waters. Feeds on aquatic invertebrates and to lesser degree, on fish. Specimens measuring 16 cm were found to be mature (Ref. 12225).
栖息于少的水流 (参考文献 12225) 的沼泽与小溪, 以及在被水淹没的大草原中.(参考文献 27188) 经常地去水的表面呼吸。 离开水面能存活长的时期。 呼吸空气在水表面的这一行为使鱼易受伤害被电鳗捕食。 (参考文献 27188) 开放水域的是一个食肉杂食动物。 吃水生无脊椎动物与达到更少的程度, 在鱼上。 测量 16 公分的标本被发现是成熟的。 (参考文献 12225)
