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.

Descrição breve
Morfologia | Morfometria
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).
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.
