how to get my zoos to open again

[hiepatitis]

i had a colony that had some fungus on it. i did an iodine dip and they seemed to open up slightly. the next day they closed up and stayed closed for two days now. how can i get them to open up again. are frequent iodine dips bad?

I would increase flow to them and possibly run just actincs for a day or so.

why the low lighting?

I believe it is less stressful on them. Whenever I get new zoas I put them in my tank with only actnic lights on.
