It depends if you want a death tank or somewhat peaceful tank.
I.E. ( death tank ) lions , triggers, bass/groupers, puffers, frog fish etc. ...... peaceful tank.... sailfin tangs/ tangs etc, large wrasses, school of anthius, large angels etc etc. It all depends on your taste.
Of coarse I wouldn't have alot of fish in the tank. Just a couple of nice show like fish.
Have fun !!!!!
