The Tang Police never miss's a beat on this board, you'll figure that out soon enough!!! Anyway, I think you should be ok, I have a 180 Reef and I have 3 Tangs (Vlegami, Mimic and a Purple Tang) They all get along fine. I honesty thinks its different in all case's, you'll just have to try it and monitor them.
Great looking tank and welcome to the board!
