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).
