I have no idea what's wrong

[BonelessEvil]

so, I've had this little guy for a couple of months. it's done fine. Now all of a sudden, the polyps are closing up. I have other Zoanthids nearby and all are doing fine. I took it out and dipped it (Revive coral cleaner), just in case I had a nudibranch issue, but it still closed up.

Any ideas?

Have you tried placing it in lower light ?

May have decided it didn’t like that area. Just had to relocate my rainbow incinerators and they re opened. Try a different area till they open.
