Any corals in a predator tank?

[reef bound]

We've got a blue spot puffer in our RSM, and one of the first things he started poking at was my beautiful red open brain coral. So, after we moved that to our 180g we noticed our zoas in the RSM were not doing well. Coincidence? I don't think so. (Those are now moved as well.) But we do have frogspawn and hammer coral, as well as colt coral and a beautiful yellow toadstool in there that he isn't bothering with. So far so good.
