Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 1 - 25 m (Ref. 9710). Tropical; 30°N - 30°S
Indo-Pacific: Maldives to the Phoenix Islands, north to Ryukyu Islands, south to the southern Great Barrier Reef; throughout Micronesia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 11.0 cm TL male/unsexed; (Ref. 2334)
(total): 11 - 12;
soft rays: 17 - 21. Occurs in three color phases: one black anteriorly and yellow posteriorly (bicolor phase), the others black dorsally with a broad white lateral band and dusky belly with or without a yellow tail.
Found solitary in abandoned tubes (Ref. 90102). Inhabit clear lagoon and seaward reefs with mixed corals and algae-covered rocks. Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
