Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Adults inhabit rocky and coral reefs exposed to mild to moderate surge (Ref. 9710). Benthopelagic (Ref. 58302). They occur solitary among boulders (Ref. 48636). Territorial in areas where filamentous algae cover rocks and dead coral (Ref. 9710). Monogamous (Ref. 52884). 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). Minimum depth reported taken from Ref. 128797.

Life cycle and mating behavior Maturities | Fortpflanzung | Spawnings | Egg(s) | Fecundities | Larven

Oviparous, distinct pairing during breeding (Ref. 205). Monogamous mating is observed as both facultative and social (Ref. 52884). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).
