Hi greg, Thanks for your question.  All adult wrasses are diurnal (active during the day).  To be honest I have seen very little information about the behaviour of the fish at night.  I would assume that they take shelter in crevices and caves on rocky reefs.  If anyone has photos or further information to add, please comment.

ARE BLUE GROPER NOCTURNAL OR DO THEY HIDE FOR THE NIGHT?
