I'm not a big fan of condies, so for this particular situation, I have no experience, so I'm only talking about potential. I've seen zoos "attack" and kill anemones. I've seen anemones go on the offensive and wipe out zoos (my BTA killed a cluster of them in my tank). I've seen them go to battle and have both the zoos and the anemone die off. I've also seen them coexist with no problems.
So, in summary, the full potential spectrum runs from "no problem" to "everything dies".
In that situation, I like to assume the worst and prepare accordingly.
