Adults inhabit deep outer-reef slopes at depths of 85-120 m, usually in the vicinity of rock outcrops with small holes and caves, and around limestone talus; usually found in small groups and observed feeding low in the water column (Ref. 59379). 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.
