They are very colourful, hence their name; males of this species are more colourful than females. Australian rainbowfish are schooling fish and will congregate near logs or riverbanks.

Authors recognised "M. duboulayi" and "M. fluviatilis" either as a single species or separate subspecies, or even as two subspecies
