identification
Cará with a cichlid body and a protractile mouth for sifting the bottom, typical of Geophagus. The difference from the acará tinga, which lives in the same waters, lies in habitat: this species prefers moderate to strong current, while the other stays in calm channels with mud and sand. It reaches 18.3 cm.
