After searching last night for them I found tons of eggs on my zoas. The thing is they are in my fuge and I only had three colonys of zoas in there, one had closed up and was moved to my girlfriends nano, I found one egg group in there, and no nudis so far. One of the other ones where closed too and I found nudis on them and just removed the zoas from my tank, they were a small colony. So now I'm down to one, which I am keeping an eye on. Hopefully I'll be able to get all of them now since they are limited to what they can eat, we'll see.
