Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 12; Rayons mous dorsaux (Total) : 14 - 17; Épines anales: 2; Rayons mous anaux: 13 - 15. Exhibits geographic color variations (Ref. 7247). Body dark in front, becoming abruptly yellow between last dorsal spine and anal fin origin (Ref. 26938).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Adults inhabit shallow coral reefs and isolated patch reefs in deeper water. Feed primarily on algae but also on polychaetes, hydroids, copepods and ascidians (Ref. 9626). Aggressively territorial but only around a small area (Ref. 9710). 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). Taken incidentally in traps and small-meshed beach nets (Ref. 5217).
