Switching tank from Reef question

[spuds]

I wont be able to get all of my zoos out, just too many attached to rocks. I know that they have some kind of toxin, however what would happen if a fish started to nibble on them? Would it be alright?

I think fish know what they can and can't eat if it's a naturally occuring organism. I wouldn't worry too much about them.
