Zoanthid won't open.

[Liquid_blue]

I picked up a new zoanthid from a LFS friday afternoon. In the store it looked fine, open and everything. WHen I get it home and put it in the tank it closed when the lights went out and never opened up again. I have purchased a zoanthid from the same shop, same tank about a month before and it is doing great and growing. Anyone have any ideas?

How are your water parameters? What type lighting do you have?

water is fine, nitrates are at 20 though but still in safe range. I have a t5 light with the 10k actinic. What gets me is my other stuff is doing fine and growing.

Is there by chance anything picking on them?

my mandarin was the first day. There was a lot of copepods on it.
