wow 200 gallon tank? this is what i would do i would drop the angel and undulated, because the angel isnt ment for a aggressive tank,(unless it is a king, but that is pufferlovers department) and the undulated is way to mean to be with other fish (imo). with a 200 i would do this setup, bursa,clown,harlequin tusk, huge puffer( large dogface or golden puffer) maybe some kind of eel/lionfish. you could even throw in a large purpple or yellow tang.
