Sick Zoa? White film

[dudluk]

I got a zoa frag over a week ago, and it looked fine, fully opened up after few hours.

Today I noticed a bit of white film, the zoas are still open, is this something that requires treatment?

Please see pictures below:

When I can remove it by delicately rubbing it:

Hw are they doing now? Did it have a smell?

As far as I remember it didn't have any noticeable smell. The white coat/film reduced after a few days, but recently I fragged that zoa and removed the fishy steam just to be safe..

So far they are doing ok, will post some pictures soon.

So the Zoa is doing ok, all frags are fine , no trace of the white thingy:

But I noticed same thing on the green star polyp, started a new thread. Cleaning it up didn't help, it came back after two days:
