I've got a couple zoo frags leftover from here:

... particularly the first colony shown, I have pieces that are a good probably 20 or so polyps each. It turned out that there were two zoos in that colony though, that had grown together, so some are sort of a greeny-yellow rimmed (as you can see in the pictures) but some were a sort of pinky-rimmed brown .. each frag I made ended up having different numbers of each.
