I just had a situation with a yellow and a purple.
I have an established yellow in my 225 and added a purple. The yellow was very aggressive towards the purple so I removed the yellow for a week. When I re-added the yellow it instantly became aggressive again towards the purple but by then the purple was healthy enough to fend so himself to a point.
After 3-4 days though the aggression stopped and they're getting along fine.
If you do decide to get more tangs I would suggest you add more than one at a time as to spread the aggression to more than one fish.
This is what I keep hearing and reading.
