Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 6 - 45 m (Ref. 90102). Subtropical
Indo-Pacific: in the western Pacific from the Ryukyu Islands south to the Great Barrier Reef, Lord Howe Island, and New Caledonia, east to Fiji and Samoa, and the Hawaiian Islands. Only the Chagos Archipelago in the Indian Ocean, but other localities are expected. The authors report the species for the Red Sea from a specimen from Sudan, one at Ras Bob on the southeast coast of the Sinai Peninsula, and one from the Seven Brothers Islands in the Gulf of Aden near the southern end of the Red Sea (Ref. 89154).
Known as widespread in the tropics south to Montague Island (Ref. 9002).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 4.5 cm SL male/unsexed; (Ref. 48637)
(total): 6 - 7;
soft rays: 7 - 9. Dorsal-fin rays VI + I,7-I,9, usually I,8; anal-fin rays I,7-I,9, usually I,8; scales usually extending forward to above pectoral-fin base, the longitudinal scale count 33–53 (mean scale count 47); body depth at origin of anal fin 10.5–17.8% SL; body progressively compressed posteriorly; head width slightly greater than head depth; snout short, the length equal to or less than orbit diameter; gill opening extending forward to posterior margin of orbit; one or two canine teeth at side of lower jaw; caudal fin truncate with rounded corners; pelvic fins short, round, and cup-like; pelvic spines short and fleshy; nape and body transparent dorsally with seven narrow red bars that broaden as they pass onto dusky golden ventral part of body (on some individuals, the red and gold tend to merge, making the bars indistinct); a white to pale yellow line visible dorsally on vertebral column. A small species, generally less than 20 mm SL (Ref. 89154).
Known to live only on sea whips and gorgonian corals (Ref. 9002). Occurs usually with Junceela fragilis in Indonesia, that found inshore on somewhat silty reefs (Ref. 48637).
