120gal mixed predatory reef tank

I've had problems with my Purple Tang nipping a clam at least twice but he usually leaves them alone. I've had to move several corals into another tank or just to a different location in the main tank because of the Tang picking on them. I've seen him bite at one of my acan, an open brain, some yellow zoanthus, anthelia, kenya tree coral, and an oulophyllia... I also blame him for the recent decline in health of a wall hammer. My frag tank is full of coral that I cant keep in my main tank because of the tang... Oh and my tomatoe clown hates xenia. If there is any xenia in my main tank she will shred it so I only have it growing in the frag tank.
