Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 12; Rayons mous dorsaux (Total) : 15 - 16; Épines anales: 2; Rayons mous anaux: 13 - 14.
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Adults inhabit shallow, coral or rocky bottoms and sometimes near the shore in areas with little visibility (Ref. 9626). Juveniles were collected from tide pools and on rocky Lithothamnion reefs; adults found up to 15 m depth (Ref. 40395). A diurnal species, adults feed on benthic algae, polychaetes and harpacticoid copepods (Ref. 9626); also consume hydroids and sponges and has been observed to feed on Abudefduf saxatilis eggs at night (Ref. 9626). 16:21 SL/TL (Ref. 9626). Oviparous, distinct pairing during breeding; eggs are demersal and adhere to the substrate; males guard and aerate the eggs (Ref. 205).
