can diff or the same butterfly fish be mixed without aggression?

I was thinking of adding some, but I don't know much about them.

I put 5 butterfly fish as the first fish in a 220 FOWLR. They were the Heniochus, Racoon, Threadfin, Longnose and Copperband. They have been in there for 10 days and their has been zero aggression. In fact much of the time they swim together. All of them are active and always looking for food.

This is the premise of my 125 FOWLR. I have a kleins and pearlscale and I haven't seen any aggression. There are some butterflies to avoid though. The raccoon, aurigua, and black back are a few. Scott Michael's book does a good job of telling which ones are aggressive and to just plain avoid.
