Adults are occasionally encountered in shallower water in caves or at the bases of overhangs (Ref. 5288). They also occur on seamounts (Ref. 057925). They are usually in pairs browsing over the rocky substratum in search of benthic invertebrates. Unknown to marine aquarium enthusiasts (Ref. 4858). Oviparous (Ref. 205).
