Some polyps on my zoa colony bot opening

[Tayreef93]

I bought a mixed colony of zoas from a local reefer a few days ago and noticed that they were all open at his house, however there seems to be always some polyps not opening since its been in my tank. Most of them are open. Im just wondering why this is happening or what could be causing it?

We could offer a million guesses, but better if you provide the water parameters, lighting, flow, and some pictures if possible, and that will help everyone help you.

Perhaps some types just take longer then others to acclimate. I have 18 different types in my zoa garden, rarely are they all open at the same time. There’s always a hermit crab or two or a shrimp crawling over them to cause them to close up at times.
