Rasboroides vaterifloris, known as the pearly rasbora, vateria flower rasbora or fire rasbora, is a species of freshwater cyprinid fish endemic to Sri Lanka. It can be found in the shallow waters of shaded, slow-flowing clear streams with a silt substrate. It also prefers areas with plentiful leaf debris. Its diet consists of detritus and terrestrial insects. This species can reach a length of 4 centimetres (1.6 in) TL. It can also be found in the aquarium trade.[2]

R. vaterifloris was formerly believed to be the only species in the genus and found in several river basins. A study in 2013 found that it was restricted to the Kalu River basin, with related species inhabiting other basins.[3] However, a comprehensive taxonomic review in 2018 based on morphometry, meristics and mtDNA found that one of the species recognized in 2013, R. nigromarginatus (also restricted to the Kalu River basin), is a junior synonym of R. vaterifloris.[4] Although this expands its range in the Kalu River basin, R. vaterifloris is more threatened than the relatively widespread R. pallidus.[4]
