I got these zoas yesterday, and only some of the polyps are/were opening up. The water in the bag smelled pretty bad, but I assumed it was the water. I added my tank water in a bucket slowly and shook it around just a little to investigate for hitchhikers. Upon placement, in my tank, a few started to open but this white film is very obvious, and many of the zoas are covered and won't open up. I know this question has been asked before, but I am a little lost on where to start or what to do to make sure I do not kill at of them by some extreme intervention. I do not have any "reef" specific dips yet but will certainly be buying some asap, and not buying from my LFS a
nymore. Any advice is appreciated as I am pretty worried and do like this little frag.
