Rasboroides is a genus of freshwater ray-finned fishes belonging to the family Danionidae, the danios or danionins.
[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.
[2] A comprehensive review in 2018 disputed this and only recognized two species, R. pallidus and R. vaterifloris (the other two considered junior synonyms).
