Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 12; Rayons mous dorsaux (Total) : 14 - 16; Épines anales: 2; Rayons mous anaux: 12 - 14. Usually with 16 dorsal spines and 12 gill rakers on the lower limb of the first arch (Ref. 7247).
Body shape (shape guide): short and / or deep; Cross section: compressed.
Adults inhabit coral and rocky inshore reefs (Ref. 9334). Omnivorous (Ref. 9334). 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).

Oviparous, distinct pairing during breeding (Ref. 205). Males guard and aerate the eggs (Ref. 205). Nests are built in holes under rocks, however, the cavity is first sandblasted thoroughly (Ref. 26281). Eggs are sometimes attached to vertical rock surface in captive fish (Ref. 39475).
