Inhabits sand and gravel runs and pools of creeks and small to large rivers (Ref. 3814, 10294). Also occurs in sandy margins of lakes. Usually found in clear creeks and small rivers and rarely in upland areas (Ref. 3814). Feeds on detritus, and small benthic and drifting invertebrates dominated by midge larvae and small mayfly nymphs (Ref. 10294).
棲息於小溪與小型到大型河川的沙與碎石小支流與水潭。 (參考文獻 3814,10294) 也生活於湖的沙邊緣中。 通常發現於清澈的小溪與小河而且極少在高地的區域.(參考文獻 3814) 吃碎屑, 與小型底棲的而且漂流無脊椎動物被蚊仔魚與小的孚游類蛹控制..(參考文獻 10294)
