Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; reef-associated; depth range 0 - 30 m (Ref. 90102), usually 0 - 10 m. Tropical; 36°N - 25°S, 92°E - 157°W
Western Pacific: southern Japan to the Philippines, Australia, and the Solomon Islands.
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 4.3 cm SL male/unsexed; (Ref. 6211)
Adults inhabit clear coastal reefs with moderate currents (Ref. 9710, 48636). Usually in small groups on sponges or reef outcrops. They feed on zooplankton (Ref. 48636). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114). Minimum depth of 0 m reported from Ref. 13227.

Estimates based on models
Preferred temperature (Ref.
123201): 25.1 - 29.3, mean 28.5 °C (based on 1875 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00617 (0.00288 - 0.01322), b=3.04 (2.86 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.4 ±0.45 se; based on food items.
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.
124155): Calcium = 373 [169, 1,160] mg/100g; Iron = 2.13 [0.94, 4.37] mg/100g; Protein = 18.1 [16.6, 19.6] %; Omega3 = 0.107 [0.034, 0.340] g/100g; Selenium = 52.9 [14.2, 175.2] μg/100g; VitaminA = 83 [17, 399] μg/100g; Zinc = 3.9 [2.0, 6.7] mg/100g (wet weight);
