Fish line up

I have a 90g tank and have had it cycled. Now I would like to add fish. So far some fish I would like to add would be a tang, cardinal fish, fire fish, a chromis and a mandarin (not until about 6 months). I was wondering what other fish everyone would recommend, or if i should take any fish out. I also need a nice hardy fish to start the tank with, however I do not want to go with a clown fish. Any advice would be greatly appreciated.
