No insult taken. Yes, I do monitor my tank at night and have not seen any of my clean-up critters bugging the polyps. I have mixed hermits, nerite snails, porcelan crab and an emerald crab- none of which have touched anything they were'nt supposed to in the time they have been in the tank. I have looked for worms, sundial snails, lesions, pox, and everything that I can think of. This is why I think it may be a fungus of some kind. Anyone that has seen my tank knows how I love my zoas and palys and this is frustrating the heck out of me. I am stuck at work until tomorrow so I do not know if the dip stopped the damage or if more are gone by now. Anyone else have any ideas?
