Usually solitary. Found in rocky, boulder strewn areas (Ref. 5227). Close relatives are known to pinch off and eat tube feet of sea urchins and other echinoderms. Also feed on crustaceans, worms and other small invertebrates (Ref. 4930). Because they live in relatively deeper waters, they are seldom collected, thus, rarely seen in the aquarium trade (Ref. 4930). Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).
