I have been checking it out at night, and a good 90% of the time it's all clear. Once or twice I've seen very small snails on it, but they don't appear to be the species of sundial snail that preys on zoa's. They look more like really small Cerith snails or something, and I usually spot them just roaming my tank elsewhere. I remove them when I see them, but I'm not sure they're hurting anything.
A part of it might be that they were improperly fragged, these four or five polyps weren't attached to the rock, he just twisted them away from the rest of the mat. They're tiny polyps, so perhaps not the healthiest specimen to begin with.
I guess only time will tell if there's an irritant in my system, it'll probly find its way over to the Eagle Eyes.
