Because of its form, this species is very easy to capture with a net. The males are very much smaller than the females. Reproduction takes place during the rainy season. The eggs are deposited on the vegetation and its incubation lasts for 30 hours. Below 6 cm, the juveniles prefer to feed on the larvae of Chironomidae and to a lesser degree on Cladocera. Then, by order of preference, they feed on shrimps, Odonata nymphs and fish juveniles of Ctenobrycon and Curimata (Ref. 12225). Frequents all types of environment (Ref. 27188).
由於它的形式 , 這種非常容易用一張網捕獲。 雄性非常遠小於雌性。 繁殖在雨季的時候發生。 卵被沈澱在植物上面，而且它的孵育持續達 30 小時。 下面 6 公分，稚魚偏愛覓食搖蚊幼生與較少吃枝角目浮游動物。 然後，藉著偏愛的次序，他們吃 Ctenobrycon 與 Curimata 的蝦，蜻蛉蛹與魚稚魚。 (參考文獻 12225) 常見於所有類型的環境。 (參考文獻 27188)
