Rasboroides is a genus of small cyprinid fishes endemic to Sri Lanka.[1] They are found in small, slow-flowing and shaded streams in the southwestern part of the island.[2] They are essentially restricted to lowlands, although one introduced population occurs at an altitude of 980 m (3,220 ft).[3] They are calm, social and attractively colored fish that sometimes are kept in aquariums.[3]

Species

Historically, there was only a single recognized species in this genus, R. vaterifloris, but in a review in 2013 four species were recognized,[2] and this is followed by FishBase.[1] A comprehensive review in 2018 disputed this and only recognized two species, R. pallidus and R. vaterifloris (the other two considered junior synonyms).[3]
