Open Zoa at night??

New tank :
Old Hobbiest
Strange question?

OK, I got a weird one guys bought a tank about 45 days ago. I now have 10 Zora Frags all healthy. My parameters are perfect everything’s on point.

So I noticed the one is not opening up during the day and at night time for what wild me out is it’s completely wide open. Here’s some photos if anyone given me any recommendations I know already. It’s not a sun coral I’ve had some corals I’ve had colonies of them. I know how bony they are. That is a Zola so just curious what you guys recommend recommendation or suggestion is it just strange to me that they’re closed during the day when everything else is open and they’re wide-open during the night when no light is on.

What type of lighting and intensity?
Are there any fish or inverts that hang around the Zoanthids?

Hey, I’m not sure where to post this. I thought I would ask for help?

I’m 99.9% sure that I have something very tiny eating my Zoas,
I’ve shined a flashlight in the middle of the night. I’ve seen something that possibly looked like a little microscopic spider that disappeared within a second of flashing the light on him. I can’t find this thing. Anybody suggest anything would a Pygmy

pinked Wrasse help?
