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).

Bayesian length-weight: a=0.01660 (0.00979 - 0.02814), b=3.17 (3.02 - 3.32), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Niveau trophique (Ref. 69278): 3.2 ±0.50 se; based on food items.

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Fec=1,000).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
