Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm ?, range 11 - ? cm
Max length : 25.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 5723); common length : 11.3 cm TL 雄魚/尚未辨別雌雄; (Ref. 12193); 最大年齡: 9 年 (Ref. 12193)
Occurs in various habitats, but most common in rocky riffles and runs of clear mountain creeks and small to medium rivers. Rarely found in lakes (Ref. 1998). Feeds on diatoms, other algae, higher plants, dipterous larvae and pupae (Ref. 1998). Spawning adults may be preyed upon by birds and mammals while small individuals may be preyed upon by stream salmonids (Ref. 1998). Edible.
出現於各種不同的棲息地, 但是常見於清澈山小溪及小型到中型河川的岩石的急流與小支流。 很少發現於湖了。 (參考文獻 1998) 吃矽藻，其他的藻類，較高等的植物，雙翅目昆蟲幼生與蛹。 (參考文獻 1998) 當小的個體可能是被水流鮭魚捕食的時候，產卵的成魚可能是被鳥與哺乳動物捕食。 (參考文獻 1998) 可食用的。
