Inhabits rapid water stretches within domain originally covered by the Atlantic Forest, posteriorly converted to cocoa plantations and more recently to cattle ranches, coffee, and rubber crops. Collected from the stretches of the rio Água Preta and rio Panelão at altitudes ranging from 162-184 m above sea level, with moderate to rapid water current, running over rock, pebbles and sand bottoms, 0.3-1.5 m deep, with rapids, pools, and meanders. Stomach contents of two specimens consisted of allochthonous and autochthonous items which included fragments of vascular plants, organic debris, insect larvae (Diptera: Chironomidae and other unidentified orders), and unidentified arthropods (Ref. 116766).
