Inhabits a broad (30-40 meters wide), clear, flowing stream with a rocky bottom. Temperature ranges between 15° and 25°C and pH from 5.0 to 6.0. During the day it shelters in the cover of undercut banks, boulders, log snags and submerged root masses, darting into crevices if threatened. Nocturnally active, feeding on insects and their larvae, crustaceans, fishes and plant matter. Sexual maturity is reached at a length of about five centimeters.
