So on a colony of zoa's i got recently, when the zoa's went in there was this orange thing that looks almost like a carpet anemonie..but kind of not that covered most of the rock all in between everyone of the zoa's. it didn't seem to be hurting them, but i could imagine that it would be sometime soon. I duno if i can get a picture of it, i can try but if someone knows w/o me geting apicture that'd be great. Its like orange black and white, and it actually has like a mouth or at least an opening that expands and contracts...any ideas?
