Short description Morphology | Morphometrics

Dorsal spines (total): 9; Dorsal soft rays (total): 19-20; Anal spines: 3; Anal soft rays: 18 - 19.

Occur in clear, current-swept terraces of seaward reefs. Observed in loose aggregations 1 or 2 meters above the bottom; juveniles and subadults typical in groups near isolated Pocillopora eydouxi coral heads and when alarmed hide themselves tightly among the branches (Ref. 9710). Benthopelagic (Ref. 58302). Feed on zooplankton and occasionally on algae (Ref. 9710, 48637, 27115, 83665). Relatively uncommon and highly localized (Ref. 1602, 9710). Very popular and hardy aquarium fish. Anterolateral glandular groove with venom gland (Ref. 57406).

Estimates based on models

Preferred temperature (Ref. 123201): 24.7 - 29, mean 27.9 °C (based on 1082 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02344 (0.01108 - 0.04959), b=2.96 (2.79 - 3.13), 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 (21 of 100).

Nutrients (Ref. 124155): Calcium = 47.6 [26.4, 81.4] mg/100g ; Iron = 0.684 [0.399, 1.139] mg/100g ; Protein = 18.9 [17.8, 19.9] % ; Omega3 = 0.148 [0.091, 0.243] g/100g ; Selenium = 29.1 [14.7, 55.1] μg/100g ; VitaminA = 74.8 [25.2, 227.6] μg/100g ; Zinc = 1 [1, 2] mg/100g (wet weight);
