Zoa illness ID

I had one frag that took weeks to finally start opening again. Was the frag happy where it was previously? Maybe try some more light

All are on the sand bed now to make them easy to move. The ones that are affected had previously been open. I'm running a 6 bulb power module and tank is 18" deep so lighting shouldn't be an issue.

I wanted to give an update. My zoas seem to be doing way better. Can't even tell there was an issue now. The fix seemed to be a dip in bifuran. I did a 20 min bifuran dip and the stuff growing on the zoa seems to be gone now and hasn't came back. Only time will tell, but overall zoa look great.
