Rasboroides pallidus is a species of freshwater cyprinid fish endemic to southwestern Sri Lanka.[1][2][3][4] It is only known from shallow, slow-flowing streams in the basins of the Kalu River, Bentara River, Gin River, Polathu-Modera River and Nilwala River.[4] It has been introduced to the Mahaweli and Walawe River basins, and is overall less threatened than the related R. vaterifloris.[5]

A comprehensive taxonomic review in 2018 based on morphometry, meristics and mtDNA disputed the validity of R. rohani, showing that it is a junior synonym of R. pallidus;[5] this synonymy is followed by the Catalog of Fishes[6] but not the FishBase.[7]

It can grow to 3.6 cm (1.4 in) standard length.[3]
