Recently I discovered my some brown pally's with white dots about the size of a pin head. I have done some research and these dont look like the pictures of zoa pox (pictures looked more like pimples). The dots are on the stems, but some pally's have white on their open faces but the dots look like splattered white paint about the size of a pin head. They are still opening up fine, and dont seem to be melting or falling off the rock they are mounted on. I have now noticed some dots (not as concentrated) on other zoas and zoos. I removed the pally's from the tank and scraped one with a scalpel. The bumps can be felt when i run the edge of the blade over them. The zoas and zoos still look very healthy other than the spots, are opening and closing and still eating when fed. The pally's dont really smell (not any more than I would expect). I just want to catch it quickly if it is fungus or pox, because I know when we notice it it is almost too late.
I have read about furan-2 dips, but heard mixed reviews on success of furan-2 with zoa fungus. I was thinking about setting up a QT, removing all zoas/zoos and dosing furan-2 or hydrogen peroxide over a week period or so. Also, are these bacteria and fungus always present in the tank but only take over when zoos are stressed? or should I be worried about remaining fungus in the tank IF i can get this under control?
Any suggestions as to what this could be and possibly how to treat? I have no pics but am hoping someone will recognize by the description.
