Descripción breve
Claves de identificación | Morfología | Morfometría
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).
Body shape (shape guide): fusiform / normal.
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).
