Inhabits rocky riffles, runs, and flowing pools of clear creeks and small rivers. Rarely found in springs and along wave-swept margins of large impoundments (Ref. 5723, 10294). Feeds on aquatic insect immatures (midges, mayflies, caddisflies) and small crustacea (isopods, amphipods, copepods) (Ref. 10294).
棲息於清澈小溪與小河的岩石的急流，小支流與流動的潭水。 很少發現於泉水而且沿著大圈圍水域的海浪沖刷邊緣.。 (參考文獻 5723,10294) 吃水生的昆蟲不成熟的 (蚊，孚游類, caddisflies) 與小的 crustacea(等足目動物，片腳類動物 , 橈腳類的動物) 。 (參考文獻 10294)
