Maturity: Lm ?  range ? - ? cm
Max length : 30.0 cm NG male/unsexed; (Ref. 89467)

Short description Morphology | Morphometrics

Dorsal spines (total): 3; Dorsal soft rays (total): 29-32; Anal spines: 0; Anal soft rays: 26 - 29. Males are straw-yellow with each scale outlined in black creating a crosshatched appearance, and a red tail with neon submarginal blue band. Females are also crosshatched, but with a slate gray to blue ground color and tail.

Biology     Glossary (e.g. epibenthic)

Found mainly around oceanic islands and near reefs along the continental coasts (Ref. 9276). Found in schools in seaward reefs above drop-offs (Ref. 9710). Benthopelagic (Ref. 58302). Feeds on zooplanktons (Ref. 89972).

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

Males establish a territory for spawning and parental care but not for feeding (Ref. 116451). Only females tend the eggs but both parents keep guard (Ref. 116451).

Estimates based on models

Preferred temperature (Ref. 123201): 21.1 - 29, mean 27.8 °C (based on 1418 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02570 (0.01232 - 0.05364), b=2.94 (2.77 - 3.11), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.28 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Fec=32,000 (from an egg cluster)).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (18 of 100).
Nutrients (Ref. 124155):  Calcium = 26.6 [10.3, 81.9] mg/100g; Iron = 0.662 [0.319, 1.736] mg/100g; Protein = 19.1 [16.9, 21.3] %; Omega3 = 0.208 [0.106, 0.407] g/100g; Selenium = 18.3 [7.9, 41.7] μg/100g; VitaminA = 56.9 [14.5, 228.7] μg/100g; Zinc = 0.584 [0.360, 0.928] mg/100g (wet weight);
