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.
