背棘 (總數) : 1; 背的軟條 (總數) : 6; 臀棘: 0; 臀鰭軟條: 11.
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 公尺的高度中出現於岩石的急流與小瀑布。 偏愛在圓石上的較深的水域 (30-60 公分) 。 (參考文獻 26172) 吃底棲的無脊椎動物例如孚游類與石蠶蒼蠅蛹，黑蠅與蚊仔魚與小的蝸牛。 卵生的.(參考文獻 205) 在夏天期間進行繁殖而且是一個在局部時間產卵的魚類。 增加抽出與河水的調節，以及污染威脅這種。
