Is it possible you have had a fluctuation in temperature?

No stays round 77 and now that's it's winter here in Michigan it doesn't go over 78. And I have the temp prob in the sump and I moved to main display and same temp. I have also looked last night for pest didn't see any

If you’re just really concerned and they aren’t glued down you can always remove them and do an iodine dip to help them overcome any dying tissue or pests you can’t see.

They are glued and I have never done a dip before. I guess I'll just let it ride and hope for best. Thanks for ur time

Zoas can be weird like that. Sometimes for no obvious reasons a colony will close up and look unhappy. A dip is probably not a bad idea, even just a quick RO dip can help.
