They are essentially restricted to lowlands, although one introduced population occurs at an altitude of . They are calm, social and attractively colored fish that sometimes are kept in aquariums.

== Species == Historically, there was only a single recognized species in this genus, R. vaterifloris, but in a review in 2013 four species were recognized, 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). {| class="wikitable" |+ !Species !Common name !Image |- |Rasboroides pallidus Deraniyagala, 1958 | |frameless|279x279px |- |Rasboroides vaterifloris (Deraniyagala, 1930) |Pearly rasbora |frameless|278x278px |}
