My first tang was a Scopas and I have since added a yellow and a Sailfin. There was some fighting from the second I placed the second tang into my tank. I attached a mirror to the side of my tank for two days and it took all the aggression out of the Scopas toward the addition. I have a 120 so with such a larger tank maybe you won’t have issues. If you do add one and see aggression, I would be prepared to intervene with a backup plan. Mirror on side glass or some other method up to removal.
