I would say you have a little room, but the established yellow tangs will be very rough on the new guy. My opinion would be no more medium to large fish, and add 1 or 2 more smaller types of fish.
Moorish Idols should really be left in the ocean, but if not, they really are only an "expert only" fish, and something like 90% of them die in captivity.
