My zoas have been under attack, by zoa eating nudi branches even a sundial snail. I thtough they had zoa pox. I think I have gotten rid of the nudis. I did the furan 2 dips, freshwater and lugols dips fresh and tank water. I don't think my zoas have the pox now or if they even had it before... All of my frags and the big colon see to be doing fine. accept this two frags of nice zoas. i don't have a name for them. One melted away completely and this last one was doing better they were starting to open up, but they were not opening all the way or they did not have the petals(I'm not sure what they are calledI had the frag at the top of the tank. I moved it down to were I want the zoa garden to be and it got knocked over once or twice, I fixed them and put them more out in the open to get more light and they just are not doing well, they are shriveling and getting white. I know its not good to move them around a lot. I am trying to keep everything stable, but I don't want to glue them unless they look like they will live.
I do water changes every week atleast 10%, M parameters are good.

here is a picture

good luck getting rid of them all i all ways dip my corals before putting them in display and if they look like not healthy i dont put them in so every thing else dont get it but try more flow and pick all nudies you can see and also keep looking good luck

I am still new at this and after dealing with this everything is getting dipped. I was not aware of how important it was at the time. I think I have taken care of the nudis I have not seen any or thier eggs in some time and aside from this one frag the rest seem to have recovered fine.

Looks like the frag didn't get moderate to strong flow after it was dipped, they need pretty good flow after that since they can slime up and get infected, like those did unfortunately. I'd give them an iodine dip and put them in good flow, but they may be goners...

The dips I did were weeks ago. They were getting better. I think I moved them out of better flow to put them were I wanted them. I moved them back to a better flow spot. Should I dip them again in tank water and lugols now?

at this point i would, what do you got to lose!! They might pull through!

Leave them alone. Unless you are certain that some parasite has taken over, your cure may cause more damage than provide cure. My zoas have melted a few times only to spring back healthier than ever. My torch does the same thing. Biology is a strange thing.
