FBname: Saint Helena butterflyfish
Comments: Common in shallow waters.  Usually observed in pairs or large groups.  Oviparous (Ref. 205), monogamous (Ref. 52884).  Form pairs during breeding (Ref. 205).  Called a cunning fish since it can nibble the bait from a hook without taking the hook into its mouth.  The juvenile <i>Thalassoma sanctaehelenae</i> has been observed cleaning the cunningfish of its parasites (Ref. 5288).
