Hello All, first post here at aquariacentral. I know you guys have a ton of experience and are very helpful so, I was hoping you might be able to assist me in identifying what these little white specks/dots are on the crown/face/fan of my little zoa frag. Initially, I believed the white dots were zoa pox. I'm no longer so certain: (a) because they do not appear anywhere on the outside of the zoa polyps (which seems to be the main indicator that your poor zoas have the pox), (b) because the zoas fully open even though they have had these little specks since day one (about three weeks ago now), and (c) because they've been through several furan-2 and/or freshwater dips. The little white specks came with the frag and were initially few in number and somewhat symmetrically spaced out across the faces of the zoas. They gradually grew in number and lost their symmetry over the course of about two weeks. I should also note that the frag is pretty tiny now because it didn't respond too well to an initial freshwater dip I gave it about a week ago. It used to cover most of the little rock its attached to (was really flourishing under the new Fluval Edge Ultrabrite system I recently upgraded to), but withered quite a bit after a 20 minute freshwater dip. As a precautionary tale to anyone else who has these awesome guys in their tanks, I'd probably recommend sticking to maybe 5-10 minute freshwater dips to prevent the same from happening. I do 30-35% water changes (RO quality) about 1.5 times a week and clean out my equipment regularly. I keep the temp at 79.8 degrees and 1.024 specific gravity. It's a 6 Gallon Fluval Edge that's been established for about three years now. None of the other tank critters seem to be nibbling on it. I also don't think that they're nudi eggs given the pictures I've seen of what they look like. So, what I'd like to know if possible is (a) what the white specks are, (b) if they're harmful to the zoas, and (c) if so, how I can more effectively treat them. Thanks in advance! Picture attached (main "infection" indicated by red circle but you'll see them on several of the other faces of the frag if you look closely). Hasn't seemed to affect my other zoas at all. I also have no idea what's going on with the three really haggard looking polyps on the larger colony - they came that way. But I just got that colony maybe a week ago so it's not connected to the white specks on the little frag.
