had these zoas for a few months, for the last few days a group in the middle hasnt been opening. ive heard zoas do this from time to time. ive examined them for bugs, but im blind and havent found anything. should i give them an iodine dip just to be sure?

IMO, yes.

ok, thanks. theyre usually really wide open, but over the last week theyve been starting to look really pathetic.

Watch them closely. You made need to dip them again a few days later. Critters aren't always the case, sometimes it can be bacterial.

it looks like theres some kind of white fuzz around the bottoms of some of the polyps...

most of them are open today, except maybe 5 in the very middle. some look pretty mangled, and some of the ones that have been closed have yellow splotches on them. idk.
