I recently received new zoa frags and upon inspection I can see white spots that seem stationary on the polyps (see pic). Are these zoa pox possibly? Is there another name for this? I can't find much information about it online, not in recent years anyway. I also have another zoa frag that has doubled it's number of polyps in a couple of months, but recently the colour on one polyp started receding. Now this morning the colour is pretty much all gone from the polyp. Pic 1: Loss of Colour Pic 2: Zoa White Spots Anyone have any thoughts advice on either of these things?
