附注 Adults typically live as commensals in the gut of shallow-water holothurians, Holothuria tubulosa and Stichopus regalis (although some deep-water records exist - Ref. 6347). Prejuveniles (tenuis larvae) probably inhabit the same host species while the vexillifer and egg-rafts are planktonic. The fish may partly protrude or entirely leave its host at night to feed on small fish and benthic invertebrates.
