簡短描述

Electric organs present.
有發電器。
Facultative air-breathing in the genus (Ref. 126274); Recorded from root mass of floating meadows in the whitewater floodplains of the Tefé region where it is common although patchy in distribution. Adults both breed and forage in the meadows and are never encountered in other floodplain habitats such as flooded forests. Both juveniles and adults feed on small aquatic animals, especially chironomid larvae (Ref. 41292).
記錄自在 Tefe 區域的白水洪泛區中的漂浮草地的根團了在那裡它是普遍雖然零碎的在分布中。 成魚在草地繁殖並且覓食而且從不在其他的洪泛區棲息地被見到例如被水淹沒的森林。 兩者的稚魚與成魚吃小的水生動物, 尤其寶刀魚仔魚.(參考文獻 41292)
