Zola’s not opening up

I'm just guessing here, but it looks like the ones that are in the shade are open. Any chance it's too much light?

Have you tried moving them? Possibly too much flow in that one spot? As someone else mentioned, the shaded ones are open.

I set them in a few different places and they seemed to like it here so I glued them down. They opened up for quite some time then all the sudden not so much. Luckily the glue snapped off and I moved them again. I do agree that the ones in a little shad seemed to open Thanks for your reply’s now we will just wait and see

How "new" is your tank? Sand and rock look pretty clean. My newest tank took a good year plus to the point where zoas would do well, even though LPS and SPS were fine. The tank may need to build up some nitrates and balance with the phosphates.
Also, are those aquacultured or wilds? I've tried the wild colonies before that come in on branch rock and have not had much luck with them.

It is on a branch. And a very new tank I’m about 5 months in now. Thank you so much for this response
