Inhabit deep slopes, subject to strong currents, with isolated outcrops of black corals (Ref. 48637). Benthic (Ref. 58302). Found in small groups. Eggs are laid on a branch section after removing the polyps and guarded by the male (Ref. 48637). Associated with antipatharian corals at depths below 15 m (Ref. 2334). Dart out to feed on small animals of the plankton (Ref. 11441).
