Synonyms [2]

Rasboroides pallidus is a species of freshwater cyprinid fish endemic to southwestern Sri Lanka. [1] [3] [4] [5] 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. [5] It has been introduced to the Mahaweli and Walawe River basins, and is overall less threatened than the related R. vaterifloris . [6]

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; [6] this synonymy is followed by the Catalog of Fishes [7] but not the FishBase. [8]

It can grow to 3.6 cm (1.4 in) standard length. [4]
