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

This species is usually encountered in clear water over coral reefs at depths between about 12 and at least 45 m. Habitats include both gradually sloping bottoms and steeper drop-offs, but in the former case it was restricted to depths greater than 20 m in the vicinity of isolated, small patch reefs. Generally, this species forms aggregations ranging from just a few fish to at least 20-30 individuals, feeding on plankton up to several meters above the bottom. The fish retreat to caves, crevices, and ledges when approached closely by divers (Ref. 75747). Life history characteristics for the family specify that this species is oviparous, with distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).
