Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Identified by the black spot found on the base of the dorsal fin; some specimens with thin transverse bands along the body but this may be attributed to the coloration before or after the reproductive period (Ref. 26543).
Feeds on algae and insects end up in the water (Ref. 26543). Tolerates extreme temperature, salinity and anoxia conditions (Ref. 26543). There was a proposal to use this species as biological control against mosquito larvae (Ref. 26543).

Produces 10 to 25 young after a gestation period of about 28 days. Young cared for by the male (Ref. 26543).
