So I was reading the zoa/paly fish predation thread and started to wonder...Chad mentioned that his nuclear hollys were taking over a rock and covering his GB zoas. I have some of the nukes in my tank and they are growing on a rock that I can not remove. Is there an easy way to keep them in check so they do not overrun the entire rock? Can you scrape them off? Not sure what the paly toxin does when you physically remove them. What about injecting them with pickling lime? I'm sure someone has removed them, I just had not thought about it and I would hate for them to cover some other cooler zoas.
