Often abundant at altitudes of 200-700 m (Ref. 33616). Benthic, nocturnally active species which usually occur solitary. Juveniles often found in large groups among leaf litter and wood debris. Movements are restricted to a relatively small stretch of river over the duration of the life span. Occur with G. marmoratus at lower elevations, but they have different habitat preferences. Feed on insect larvae, fishes, fish eggs, earthworms and crustaceans. Breed between October and December. Sexual maturity is attained after 2 years (Ref. 44894). Often caught by recreational fishers targeting trout, although not a desirable target due to its small size (Ref. 33616). Allen, G.R. 1989 Freshwater fishes of Australia. T.F.H.
