A cool-water species not found below 600m altitude; occurs in deep pools and flowing waters of permanent rivers and in dams (Ref. 52193). It feeds primarily on algae in winter months and aquatic insects in summer months, but also takes mussels, snails, crabs and small fish (Ref. 52193). Breeds during spring and summer, males maturing at a smaller size (170 mm FL) than females (300 mm FL); females grow larger than males (Ref. 7248, 52193).
