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]
