Korte beschrijving
Determinatiesleutels | Morfologie | Morfometrie
Dorsale zachte stralen (totaal) : 15; Anale zachte stralen: 13. Usually with 14 or 15 spines and 10 or 11 gill rakers (Ref. 7247).
Adults inhabit coral and rocky reefs (Ref. 9334). Somewhat territorial, they chase away small intruders (Ref. 5227). Omnivorous, they graze on algae and nibbles at 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).
