Colouration: pale pinkish to yellowish with red to brown blotches, radiating bands from eye; body protuberances are white, appearing as white spots (Ref. 80667).
Found in association with the soft coral Nephtea, but has also been observed swimming lengthy distances from one coral to the next (Ref 90102).
