Biology     Glossary (e.g. epibenthic)

May be seen in a variety of habitats ranging from rich coral reefs (Ref. 58652 ) to weedy and rubble covered areas (Ref. 1602 ). Benthopelagic (Ref. 58302 ). Maybe found singly, in pairs, and in aggregations that roam over large distances in search of food. Feed mainly by tearing pieces from polychaetes, sea anemones, coral polyps, and algae (Ref. 1602 ). Oviparous (Ref. 205 ). Form pairs during breeding (Ref. 205 ). Minimum depth reported taken from Ref. 128797.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Distinct pairing (Ref. 205 ). Monogamous mating is observed as both obligate and social (Ref. 52884 ).

Estimates based on models

Preferred temperature (Ref. 123201 ): 25.5 - 29, mean 28 °C (based on 922 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.02512 (0.01625 - 0.03883), b=2.98 (2.85 - 3.11), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.7   ±0.3 se; based on diet studies. Resilience (Ref. 120179 ):  High, minimum population doubling time less than 15 months (K = 1.5;). Fishing Vulnerability (Ref. 59153 ):  Low vulnerability (23 of 100). Price category (Ref. 80766 ):   Unknown . Nutrients (Ref. 124155 ):  Calcium = 93.2 [46.4, 155.6] mg/100g; Iron = 0.905 [0.498, 1.574] mg/100g; Protein = 19 [18, 20] %; Omega3 = 0.126 [0.071, 0.224] g/100g; Selenium = 46.9 [24.0, 94.1] μg/100g; VitaminA = 30 [8, 113] μg/100g; Zinc = 1.26 [0.82, 1.89] mg/100g (wet weight);
