I recently added some peppermints to my reef and they seem to be very shy. Is this a common behavior? Whenever I see them they are swaying back and forth as if they are stressed. Is this normal and do they eventually come out?
If they sway back & forth when they see you then they are asking if you want to be cleaned.
Grab a piece of fish food and stick your hand about 6" away from them until they climb on and "clean" you.
