Comments: A freshwater fish that is unable to undertake diadromous migrations. Typically recorded from clear water in slow to moderately flowing creeks to large rivers (1.0-12.0 m average width and 0.1-0.6 m average depth), flowing through light to heavily forested (and shaded) catchments, consisting mainly of pools, glides and riffles with smaller areas of still backwaters. It is also recorded from modified streams in areas almost completely cleared for grazing. Substrate often consists of bedrock, boulder, cobble and coarse sand with smaller amounts of pebble, gravel and silt. Instream cover is typically provided by rock, timber debris, and smaller amounts of aquatic vegetation, leaf litter and bank and vegetation overhang. Average pool depth ranged from 0.2-1.8 m. It is collected at densities ranging from < 0.1-1.5 fish/m2  and found with other native fish species Shortfinned eel, <i>Anguilla reinhardtii</i> (Longfinned Eel), <i>Retropinna</i> sp. (Eastern smelt), and River Blackfish, native decapod crustaceans, Common Freshwater Shrimp, East Gippsland Spiny Crayfish and Variable Spiny Crayfish (<i>Euastacus yanga</i>), and a native bivalve mollusc (<i>Hyridella</i> sp.). Recorded with the alien species Brown Trout, though probably occupies a discrete micro-habitat (Ref. 98815).
