Rasboroides is a genus of freshwater ray-finned fishes belonging to the family Danionidae, the danios or danionins. The fishes in this genus are endemic to Sri Lanka. [2] They are found in small, slow-flowing and shaded streams in the southwestern part of the island. [3] They are essentially restricted to lowlands, although one introduced population occurs at an altitude of 980 m (3,220 ft). [4] They are calm, social and attractively colored fish that sometimes are kept in aquariums. [4]
Historically, there was only a single recognized species in this genus, R. vaterifloris, but in a review in 2013 four species were recognized, [3] and this is followed by FishBase. [2] A comprehensive review in 2018 disputed this and only recognized two species, R. pallidus and R. vaterifloris (the other two considered junior synonyms). [4] [5]
