I've got a struggling and small zoo colony on a rock that would be perfect for an acan. I can't easily remove the zoos and they are slowly melting away. They were in bad shape when I got them (for practically nothing), so I don't care if they go away. If I place a couple of acan polyps on the rock next to the zoos, will the acan ultimately cover them up and overtake the rock? That's what I'm hoping for, but wonderjg if anyone has experience with acans and zoos side by side.
