Épines dorsales (Total) : 13; Rayons mous dorsaux (Total) : 14 - 15; Épines anales: 2; Rayons mous anaux: 13 - 14.

Adults are found among coral outcrops and seagrass beds of silty areas of lagoon and coastal reefs (Ref. 9710), usually subtidal to a few meters depth (Ref. 48636). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Diurnal species (Ref. 113699).

Estimates based on models

Preferred temperature (Ref. 123201): 27.7 - 29.3, mean 28.8 °C (based on 1620 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01479 (0.00642 - 0.03409), b=3.00 (2.80 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 2.0 ±0.00 se; based on food items.

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Nutrients (Ref. 124155): Calcium = 110 [57, 188] mg/100g; Iron = 0.801 [0.460, 1.337] mg/100g; Protein = 18.5 [17.3, 19.6] %; Omega3 = 0.109 [0.063, 0.186] g/100g; Selenium = 17.6 [9.7, 35.3] μg/100g; VitaminA = 108 [30, 394] μg/100g; Zinc = 2.32 [1.55, 3.32] mg/100g (wet weight);
