More on author: Herre.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; reef-associated; depth range 8 - 25 m (Ref. 9710). Tropical; 25°N - 18°S
Western Pacific: Japan to Western Australia and the Solomon Islands.
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 10.0 cm TL male/unsexed; (Ref. 9710)
Dorsal spines (total): 1 - 2; Dorsal soft rays (total): 29 - 33; Anal spines: 0; Anal soft rays: 25 - 30. Dark brownish green to grayish green head and back, lower portions noticeably whitish; dark brown to pale orange iris; dark brown lips. Caudal fin membranes usually orange anteriorly, dusky posteriorly; other fins clear; spinous dorsal similar to body color. Pelvic fin rudiment moderate in size, broadly attached to posterior margin of ventral flap. Midbody scales variable in size. Scale rugosities in males usually develop at about 50 mm SL. Varies considerably with respect to squamation, coloration, fin-ray counts and max. size across its range.
Secretive species found in lagoon and protected seaward reefs (Ref. 9710, 48637), often in silty conditions. Solitary (Ref. 90102). Sometimes seen deep inside branching corals (Ref. 48637). Has been from deeper water by trawls.

Estimates based on models
Preferred temperature (Ref.
123201): 27.8 - 29.3, mean 28.8 °C (based on 1722 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00956 - 0.04164), b=2.93 (2.76 - 3.10), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.9 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
Nutrients (Ref.
