The species is a carnivore, taking a wide range of foods including meaty frozen foods, sinking pellets and detritus gathered from the rockwork.
Compatibility
The Aquairi knowledge base lists this species as semi-aggressive. Suitable tank mates include Larger fish, Hardy corals. It should be kept away from Small slow fish, Feather Dusters, Small shrimp. This species is not fully reef-safe and may pick at corals, sessile invertebrates or small tank mates.
Breeding
Breeding requires an extended planktonic larval stage in open water before the young settle, which makes captive reproduction very difficult and rarely accomplished in home aquaria. Most specimens in the hobby are wild-collected.
