生物學特性     字彙 (例如 epibenthic)

Adults found in exposed seaward reefs. Sometimes inhabit clear lagoons or channels. They occur in small to large aggregations on the upper edge of the slope over live coral or rubble. Uncommon (Ref. 9710). Benthopelagic (Ref. 58302). Feeds on planktons (Ref. 89972). 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). Minimum depth reported taken from Ref. 128797.

發現於裸露的臨海礁石了。 有時居住於清澈的潟湖或峽道。 在活珊瑚或碎石上的斜坡上緣上形成小群到大群魚群。 罕見.(參考文獻 9710)

Estimates based on models

Preferred temperature (Ref. 123201): 25.4 - 28.4, mean 27.4 °C (based on 140 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00579 - 0.02736), b=3.03 (2.84 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (Ref. 69278):  3.0   ±0.2 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  高度, 族群倍增時間少於 15個月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Nutrients (Ref. 124155):  Calcium = 216 [121, 486] mg/100g; Iron = 1.29 [0.76, 2.23] mg/100g; Protein = 18.4 [17.2, 19.5] %; Omega3 = 0.181 [0.093, 0.348] g/100g; Selenium = 22.6 [10.2, 47.8] μg/100g; VitaminA = 275 [91, 854] μg/100g; Zinc = 2.68 [1.71, 3.93] mg/100g (wet weight);
