soft rays: 7 - 9. Characterized by semi-transparent head and body with white internal pigment over brain; upper surface of vertebral column white internal white stripe; ventral half of body with six faint reddish internal bars; lower half of body obscured by reddish brown to violet brown or purple streak and ending at caudal fin base; presence of brown saddles along back; all pectoral rays usually unbranched; longitudinal scale series 34-49; broad and disc-like pelvic fins, reaching to anus or beyond; opening of gill usually reaching to below rear edge of eye (Ref. 90102).
Lives on certain branching coral forms of fire coral (Millepora spp.) and on other massive corals ones (e.g. like Porites cylindrica, P. lutea) in shallow lagoons at depths of 1 to 10 m.
