They have a brownish-grey colored body with a black face mask highlighted by yellow markings from around the eyes down to the mouths bright orange lips.
The dorsal fin is blue at the base, then black, and then ends with a white band along the outer margin. The anal fin is brownish orange at the base, turning to a brighter orange, with the outer margin trimmed in white. The tail has a crescent shaped border that is white inside, changing to a pale yellow color on the outer edge.
