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.
亞洲: 在 Pallegama 的卡盧河中侷限於 Knuckles 的斜坡東部希爾了, 在海拔 300-500 公尺的斯里蘭卡。 非常稀有而已知唯一的現有族群是由於卡魯河上游開採珠寶礦石產生的淤泥的即將滅絕。

簡短描述
型態特徵 | 形態測量圖
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 的成魚被藉由在身體臀鰭前面起源上持有一個突出的黑色斑紋與 P. filamentosus ， P. singhala 與 區分 P. assimilis 。 他們不同於 P. exclamatio 藉由缺少一個延長 , 淚滴-形狀的黑色斑塊上方與臀鰭; 從 P. arulius 與 P. tambraparniei 藉著具有嘴下方的與下唇中間地不存在 ( 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.
一個中層水域魚用多礫石的底部發現於快速流動水的區域了。 (不出現在淤泥的底部) 具有一個界線明確的領土 (一些平方公尺)而且沒有橫向空間的偏愛。 相同的大小的個體時常形成鬆散的魚群。 目前不是有用在足夠的數量中被輸出藉由水族貿易。
