Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 12; Μαλακές ραχιαίες ακτίνες (συνολικά) : 14 - 16; Εδρικές άκανθες: 2; Μαλακές εδρικές ακτίνες: 12 - 14. Usually with 16 dorsal spines and 12 gill rakers on the lower limb of the first arch (Ref. 7247).
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).
Life cycle and mating behavior
Maturities | Αναπαραγωγή | Spawnings | Egg(s) | Fecundities | Προνύμφες
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).
