Some zoas closed up...

[clown and friends]

A few of my zoa frags are all closed up and have been like this for days and I am not sure why as there are plenty of others that look great. Any ideas as to why they could be like this? Should I FW dip them and see if anything comes out?

Neat clams! Can't tell if they're in the corner of the tank but if they're new frags make sure you acclimate them to the light correctly. Might get mad at me even if I move the light an inch

They've been in the tank for at least 2 months, I changed lighting about a month ago (for the clams in the pic lol) but it wasnt until the last week or so they've looked like this

Not sure about FW dipping, but an iodine dip would be fair game.

Edit- iodine dip if you think there's some sort 9f infection, or a bayer/coral rx dip if suspect pests.
