Zoa help

[Tschupe]

What is causing the polyps to shrink like this? It was just 1 now 3 are doing it. I took them out and dipped them but no pests came off.

I have some zoas doing the same. I dipped mine in tank water with lugols solution ( 10 drops) and left them in to soak for 10 mins and places them back into the tanka and leave them alone. I find it that the more you mess with them, they more stress out they become.

Mines are slowly starting to open up. Even my small 5 polyp cluster of fruit loops did the same and theyre slowly opening back up after the dip a couple days.
