Should I use my 56 zoa colonies as food?

Your not going to like this, but the buterfly went after our zoas once he finished of with the apatasia. I hated to dismantle all the rock work to catch him, but off to the FOWLR he went. Did his job there then got taken down by our octopus. So now i live with them, when they get to big i hit them with app-x. Works realy well, but it has to be done is still water. They don't seem to come back after the treatment.
