Colour: White with three broad black bars. The first diagonal bar from nape and upper head through eye to chin. Caudal fin pale.

Remarks: Dascyllus aruanus is sometimes confused with D. melanurus (not recorded from the Maldives). They are easily distinguishable when seen together. The position of the anterior black bars and the lack of black on the caudal fin will serve to identify D. aruanus.
