Question about coral

[kevincoral2020]

I had this new coral, I don’t understand why it is not open up, all my water parameter are fine, what should I do? And I have move the coral to other side of tank so it would be by itself.

Wont get much replies unless you post your water parameters. Lighting also is in question. How old is the tank. Seems like a large coral to just buy? Where did it come from. How long is new.
