Tang has a risk of ich if not careful. For your tank wise, once your tank stabilizes and for a while more, can explore torch coral, (alveopora/goniopora) are tougher to keep.
If all your rocks are filled with zoas also very beautiful. Heheh. If you are keen to keep Anemone to host ur clown, beware as it may moves and injure other corals.
Take a look at Golden octopus for some ideas. See many many lps there. But google and confirm ur tank para/light can take it if not your $$ goes to waste.
