Flasher Wrasse maybe sick?


Well I have a beautiful flasher wrasse in my tank and he seems to be doing well for the most part but for the last couple days hes been hanging out at the water line a lot just in the same spot still swimming fine he ate this morning but didnt eat just right now. He doesnt have any noticeable diseases like ich or anything but i was just worried so i thought i'd post. see if its something i can catch or hes just bein dumb
