Comments: A freshwater fish that is unable to undertake diadromous migrations. Collected from cold and clear water in small flowing creeks (0.6-1.1 m average width, 0.1-0.2 m average depth, 0.5-0.6 m maximum depth) and from an on-stream lake (Blue Lake). All sites during winter are covered by snow and ice for an extended period of time. Substrate in the creeks consisted of bedrock, boulder, cobble, gravel and sand while the lake with cobble, pebble, gravel and silt.The fish is collected among rock, undercut banks and overhanging grasses in the creeks, mainly from pools. In Blue Lake, collected among small cobbles and from within 2 m of the shoreline (location and habitat in deeper water unknown). All sites without emergent or submerged aquatic vegetation or overhead shading. Collected at a density of 4.5 fish/m2  in Carruthers Creek, 2.5 fish/m2  along the edges of Blue Lake, and 1.5 fish/m2  in an inflowing tributary to Blue Lake. It is the only native fish species so far recorded from within its range, although <i>Galaxias olidus</i> is presumed to be present nearby. It is collected in Carruthers Creek with an unidentified native spiny crayfish <i>Euastacus</i> sp. (possibly <i>E. rieki</i>) (Ref. 98815).
