Asia: restricted to the eastern slopes of the Knuckles Hills in the Kalu River at Pallegama, Sri Lanka at elevations of 300-500 m. Very rare and the only known existing population is in imminent danger of extinction due to the siltation of the Kalu caused by gem mining upstream.

简单描述
型态特徵 | 形态测量图
Adults of Puntius srilankensis are distinguished from P. filamentosus, P. singhala and P. assimilis by possessing a prominent black markings on body anterior to anal-fin origin. They differ from P. exclamatio by the absence of an elongate, tear-shaped black blotch above and anal fin; from P. arulius and P. tambraparniei by having mouth inferior and lower lip medially absent ( vs. mouth subterminal, lower lip entire) (Ref. 55036).
Puntius srilankensis 的成鱼被藉由在身体臀鳍前面起源上持有一个突出的黑色斑纹与 P. filamentosus ， P. singhala 与 区分 P. assimilis 。 他们不同于 P. exclamatio 藉由缺少一个延长 , 泪滴-形状的黑色斑块上方与臀鳍; 从 P. arulius 与 P. tambraparniei 借着具有嘴下方的与下唇中间地不存在( vs. 嘴接近端位的, 下唇整個的).(參考文獻 55036)
描述: 胸鰭有一單一的與 15個分支條。 在身體上側線有 21 或者 22個鱗片, 在尾鰭基底上有 1-2 個鱗片.(參考文獻 55036)
A mid-water fish found in areas of rapidly flowing water with pebbly substrate (not found in silty substrate). With a clearly defined territory (of several square meters) and without lateral spatial preferences. Individuals of the same size often form loose schools. Presently not available in sufficient numbers to be exported by the aquarium trade.
一个中层水域鱼用多砾石的底部发现于快速流动水的区域了。 (不出现在淤泥的底部) 具有一个界线明确的领土 (一些平方公尺)而且没有横向空间的偏爱。 相同的大小的个体时常形成松散的鱼群。 目前不是有用在足够的数量中被输出藉由水族贸易。
