Zoos not opening all the way

[spivack]

I have a 3 inch colony of "buble gum" zoos.they are open but not all the way. The skirts do not come out. I do not see anything physically bothering them and my other zoos are fully open.

Any ideas?

Can you list your parameters across the board?

When was your last water change?

How much current ( movement ) do you have circulating in your tank?

If it was a predator the entire polyp ( colony ) would retract.

Have you tried running your actinics only for one full day? Do so after a brief water change.

What additives are you using?

Are you dosing iodine?

How long have they been in your tank and in this condition?

did you just add them to your tank or have they been in there for awhile.
