Rasboroides is a genus of small cyprinid fishes endemic to Sri Lanka. They are found in small, slow-flowing and shaded streams in the southwestern part of the island.[1] They are essentially restricted to lowlands, although one introduced population occurs at an altitude of .[2] They are calm, social and attractively colored fish that sometimes are kept in aquariums.[2]
Historically, there was only a single recognized species in this genus, R. vaterifloris, but in a review in 2013 four species were recognized,[1] and this is followed by FishBase. A comprehensive review in 2018 disputed this and only recognized two species, R. pallidus and R. vaterifloris (the other two considered junior synonyms).[2]
