Not sure, but a good thing to post are your water parameters and any major changes to the tank (lighting changes, filtration media etc) so that others have some more information to go off of.
IME... I wouldn't worry too much about it. Some of mine do it randomly and are back to normal in an hour or a week. I've never tried to move them when I see it happen and it's never hurt any
Ok thanks. Hopefully it’s ok while I’m gone hunting for the week. On my way home from hunting I’m picking up a 225 acrylic tank. I think I’ll do a build thread. I will have a 150 gallon sump in my basement. What I’m getting at is all of my corals will be moving soon anyways.
