Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 12 - 183 m (Ref. 11013), usually 25 - 50 m (Ref. 47838). Tropical; 30°N -
Eastern Central Pacific: Hawaiian and Johnston islands.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 18.0 cm TL male/unsexed; (Ref. 3921)
soft rays: 18. Overall pale with a broad black bar bordered by a narrow pearly white band running across the upper side from the front of the eye to the posterior portion of the soft dorsal fin. A similar broad black band with pearly white border runs submarginal on the caudal and anal fins.
Common on rocky reefs, in ledges and caves; also in coral areas (Ref. 47838). Benthopelagic (Ref. 58302). Submarine observations to 183 m (Ref. 11013). Feeds mainly on sponges (Ref. 47838); stomach content of some specimens also had algae, traces of hydroids and unidentified eggs. Minimum depth from Ref. 47838.
