Zoa's Closed up

[BonesCJ]

All the Zoa's in my tank have been closed up for the last several days, all my other corals including SPS, LPS, Mushrooms, Leathers, GSP's, and Xenia are all doing great. The two things I suspect are either my Coral Beauty Angel as I have seen him pick at one or two or the fact that I ran my tank without carbon for about a week and maybe the leather toxins got to them. Any Suggestions?

I would run carbon, angel would have to be a pest to get all of them to stay closed in a 72 gal. unless its just one or 2 colonies

Yeah i got carbon in just a couple days ago, I have 1 mega colony and at least 5 frags scattered all over the tank, the coral beauty does not seem to be targeting them, he just picks at the rocks looking for algea and gets ahold of one every now and then.
