Descrição breve
Chaves de identificação | 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).
Body shape (shape guide): fusiform / normal.
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.
