Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 10.0 cm TL male/unsexed; (Ref. 30874)
Adults are found under stone or corals in flood basins and lagoons (Ref. 9137). They are common but very secretive and usually found when turning rubble pieces in pools (Ref. 48635). They venture out in the open at night to feed on small crustaceans, fishes and gastropods (Ref. 37816). Eggs are guarded by the male parent (Ref. 205). Minimum depth reported from Ref. 30874.

Estimates based on models
Preferred temperature (Ref.
123201): 24.8 - 29, mean 27.8 °C (based on 954 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00468 (0.00175 - 0.01251), b=3.18 (2.95 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.6 ±0.3 se; based on diet studies.
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).
