Most of the heads are open but some are closed
ok, any more detail you can give? Pictures may also be of great help. The ones that are open, are they looking healthy? I'll have colonies that most will be open, but some will stay closed, then maybe the next day or the day after they are open again.
What kind of lighting, timing, placement, nearby corals, fish that may nip? Have you watched them after a few hours of lights out to see if anything comes out and aggravates them?
Has anything changed in your tank recently?
Details are your friend, my friend :bigsmile:
There are so many possibilities that without some more details, we're shooting in the internet dark here.
They look pretty healthy to me...
Something could have irritated the ones that are closed up. How long have they been closed up for?

I've had this frag for a few months. I just got home and snapped a pic for you. You can see that there are a few in there that are closed up. I'm not worried, the rest look healthy (to me) so, I'm not going to mess with him.
NO. just let them set and acclimate. From what I have found common zoas like these are pretty tolerate to just about any light you toss at them. Other experts will likely chime in...Here are some photos that MAY help.
While they are not the subject of this photo, the zoas against the back wall about where the ruler is pointing.. they are reaching.
as compared to these which are not.
