Zoas won't fully open - Please help identify possible infection
 

Hello folks,

I have an older thread about my unhappy Zoas, so some may be familiar with them :).
When I bought them they were all open and beautiful but they have never thrived in my tank. I have tried moving them all over the tank and let them sit for a few days but there is no improvement.
I looked close for signs of Pox but my newbie eyes didn't see any so I decided to take a video and post it in here to see if anyone sees a sign of any possible infection.
Please let me know if you have issues with the link:

Your help is as always greatly appreciated.

Anyone ,please?

Did you dip? One of mine must have had nudibach eggs because they went from great to closing up and disappearing. I dipped and a nudibrach fell off. Then a few weeks later dipped again and more fell off. Hopefully the last of them! So even if you dip, that only kills adults and you might need to dip again. Just a thought.

Could be nudis or pests, could be they weren't getting enough flow in previous spots (they're good in the video spot I would leave them there), or it could be that you keep touching them and moving them all over the tank every few days.

Check them thoroughly for pests then leave them alone.

I decided to do a cycle with Foran 2, even though I didn't see any signs of infection. They started to open up right after the first treatment. Hopefully is not just me being hopeful and they really turn around.

Thank you all!!
