One of the most colorful species of the genus, especially during its reproductive period. Frequently occurs in zones with little current and over a substrate covered with vegetal debris (Ref. 27188). Caught frequently but not abundantly in most varied biotopes- in small creeks and flooded zones with clear, shallow and slow flowing water. Feeds primarily on insects, secondarily on fishes and plants. Very territorial. During reproduction, males attain a deeper coloration. About 1,000 eggs are released during spawning. Spawning takes place on stone or wood. Parents take care of juveniles (Ref. 35237). Maximum length 25 cm TL (Ref. 1672).
