Zoas closing up a bit

[ltrot92]

I recently attached a zoa frag to a chunk of live rock, and while for a few weeks it was doing fine, last week I notices that one of the heads didn't open all the way. At the time I assumed that this was simply because it had been disturbed and would slowly open up given time, but that doesn't seem to be the case. Today while looking at my tank i noticed that it's spread to three polyps. My params all seem fine, and most of my other corals seem okay (my duncan was closed up for a bit but he's opened up again) so any advice would be appreciated!

I’ve had zoa’s close up from time to time. Eventually they reopened

My zoas act up every now and again. Some colony’s more than others. I haven’t figured it out yet, but they always look good again a week or so later.
