Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 15.0 cm TL male/unsexed; (Ref. 4392)
soft rays: 8. Body variable from brown to yellow or green mixed with various color shades or spots. Males develop long filaments on the caudal fin (Ref. 48636). Young with a broad, dark lateral stripe which breaks into dark blotches in adults, the largest above distal pectoral fins. A small dark spot behind eye. Mouth terminal or lower jaw slightly projecting. Caudal fin of terminal males rhomboid, with central rays longest, and dorsalmost caudal-fin ray elongated into a short filament. A small species (reaching about 14 cm) (Ref 9823).
Inhabits outer reef slopes or deep clear lagoons among rubble or clumps of algae; also in seagrass beds (Ref. 1602, 41878, 58302). Often in sheltered estuaries and harbors (Ref. 48636). Benthic and benthopelagic (Ref. 58302).
