Found in rocky rapids and cascades in altitudes of 900-1,200 m; prefers deeper waters (30-60 cm) over cobbles (Ref. 26172, 52193). It feeds on benthic invertebrates such as mayfly and caddis fly nymphs, blackfly and midge larvae and small snails (Ref. 52193). Oviparous (Ref. 205). Breeds during summer and is a partial spawner (Ref. 52193). Increasing extraction and regulation of river water as well as pollution threaten this species (Ref. 7248).
在 900-1,200 公尺的高度中出现于岩石的急流与小瀑布。 偏爱在圆石上的较深的水域 (30-60 公分) 。 (参考文献 26172) 吃底栖的无脊椎动物例如孚游类与石蚕苍蝇蛹，黑蝇与蚊仔鱼与小的蜗牛。 卵生的.(参考文献 205) 在夏天期间进行繁殖而且是一个在局部时间产卵的鱼类。 增加抽出与河水的调节，以及污染威胁这种。
