Morphology | Morphometrics
soft rays: 8;
Vertebrae: 29 - 31. Distinguished from all other Rasbora species by its distinctive markings and coloration. It differs from its closest congener, Rasbora kalochroma in having a vertically oval dark blotch (versus absence of such a blotch) at the caudal base and lacking (vs. having) a well-defined blackish band across the middle of the caudal fin (Re. 13217).
Occurs in lowland streams and swamps, with tannin-stained, brownish to black, acidic freshwater of pH 4.1- 6.1.
