Orange zoos not opening

[WickedReefer]

I have some bright orange zoos in my 20gallon that are not opening. They seem to have some brown algae on their tissue, but even when I brush it off with a toothbrush they still won't open. I have some other zoos in there with them, but they seem to do fine. Any suggestions? Heres a list of what I have in it:

Corals:
Purple hairy mushrooms
Bright green candy canes
Purple candy canes
Plain green candy canes
Pom pom Xenia
GSP
Mushrooms
Monti Cap
Zoos (about 6 different colors
Pink Pocilipora
Small Toadstool Leather
Small fungia
Small Yellow Turbinaria (the polyps are not opening either)

Fish/Inverts:
Two emerald crabs
Two pom pom crabs
Candy Pistol shrimp
Margarita Snails
Exquisite Wrasse
Yasha Hase Goby
Five Nasairius Snails

I have a 24" compact light on it and everything as far as tests go are fine. I had some very nice Purple with green skirt palys, but they died once they stopped opening up.

How long have you had it? Any sign of zoa pox (tiny whitish spots)?

not that I know of. I've had the zoos for over a year now. It started as a frag and now its a small colony sharing space with some orange centered green skirt zoos and a monti cap.

I had some that did the same thing.

The appearance did not look like zoa pox, but over a month or so my entire eagle eye colony (enclusting a large rock) dissappeared. It started out with another large colony of zoa. This one almost died off but recovered. No so lucky with eagle eyes. Other zoa including blue ones are not affected at all while that was going on.

I recently tried Furan-2 dip with a good size eagle eye frag and a small colony of similar zoas which appeared to have started doing the same dissapearance act. The dip seems to have helped (knock on wood).

I'll try to do that is there a certain type of dip you use or did you use something like Lugol's?

I use Furan-2 for the zoa that do disappearing act.
