Biology     Glossary (e.g. 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).

Estimates based on models

Preferred temperature (Ref. 115969): 23.5 - 28.1, mean 24.4 °C (based on 27 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01862 (0.00888 - 0.03903), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this Genus-BS (Ref. 93245).
Trophic level (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.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (tmax=27).
