生物学特性     字汇 (例如 epibenthic)

Adults inhabit coral and rocky reefs (Ref. 9334). Omnivorous (Ref. 9334). Adults are territorial and aggressive, vigorously driving off other fishes and certain invertebrates from their feeding and reproductive territories. They graze on algae and invertebrates including tubeworms, small crustaceans, and the tentacles of anemones (Ref. 28023). 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).

栖息于珊瑚礁与岩礁。 (参考文献 9334) 杂食性.(参考文献 9334) 成鱼是具有领域性而侵略性,强有力地驱逐来自他们的摄取食物与生殖领土的其他的鱼与特定的无脊椎动物。 啃食包括管虫,小型甲壳动物 , 与卷曲异辐海葵的触须的藻类与无脊椎动物。 (参考文献 28023)

Estimates based on models

Preferred temperature (Ref. 123201): 23.5 - 28.1, mean 24.4 °C (based on 27 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01950 (0.00893 - 0.04257), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.0   ±0.39 se; based on food items.
Generation time: 1.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
