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. One of the most recently discovered Australian freshwater fish species (Ref. 44894). Pusey, B.J. and M.J.

The river reaches were a mixture of cascade sections, runs and deep pools. Water velocities from greater than 1 m/sec in the cascade sections to 0.03 m/sec in the pools. In-stream cover limited to boulders, some bank undercutting and associated rootmasses and sparse wood debris. When disturbed, rapidly seeks cover within the cracks and tumbled slabs of granite on the bed. A microphagous carnivore. Feeds mainly on aquatic insect larvae - mayfly nymphs (18%); chironomid larvae (17%), pyralid larvae (13%) and trichopteran larvae (6%); the 28% comprised of unidentified arthropod fragments. The food consumed indicate that foraging was mostly limited to the benthos; however, some individuals also foraged at the surface with terrestrial invertebrates (7%) and terrestrial plant matter (1%).
