大小 / 重量 / 年龄
Maturity: Lm ? range ? - ? cm
Max length : 30.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 6028)
Occurs in a few localized, rocky, fast-flowing mountain streams. Has not been recorded from unshaded, silty or turbid waters (Ref. 11966). Moves fast through the water, staying close to the bottom. Juveniles have been observed picking algae off submerged rocks. Feeds on algae. Occurs sympatrically with (and possibly mistaken for) Puntius sp. 'martenstyn' throughout the known range. May be greatly endangered by the damming of Mahawel River. Too rare and difficult to capture for food.
出现于一些本土化, 岩石又快速流动的山地溪流。 没有被从无遮蔽的，淤泥的或浑浊的水域记录。 (参考文献 11966) 移动快速的经过水, 停留接近底部。 稚鱼曾经观察采集藻类外海的水下岩石。 吃藻类。 在已知的范围各处与 Puntius sp.'martenstyn' 生存分布区重叠 (而且可能地被误认为) 。 可能是非常濒临绝种藉由 Mahawel 河的水坝。 太稀有而困难的捕获作为食用鱼。
