Like all species of the genus, it is abundant in small, slow-flowing, shallow creeks with rocky-silty bottom. Occurs together with Guianacar owroewefi, Pyrrhulina filamentosa, Cyphocharax spilurus, Hemigrammus guyanensis and Heptapterus longior. Feeds on small crustaceans and insect larvae. Males are a little bigger and more colorful than females; they have elongated anal, dorsal and ventral fins, the latter exceeding the origin of the anal fins. The parents clean the flat stone where about 500 eggs will be spawned. Parents show a marked territorial behavior during this the spawning period (Ref. 35237).
