Morphology | Morphometrics
Adults occur inshore (Ref. 7300) at depths of 12 m or less in dead coral, reef flats, and on coral heads, habitats with somewhat less wave energy (Ref. 27772). Eggs are guarded by the male parent (Ref. 205).

Bayesian length-weight: a=0.00468 (0.00173 - 0.01268), b=3.18 (2.95 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
