WW3 in my tank help!

[Elrond]

I could use some advice, I recently added a md powder blue and small purple tang to my 300 gallon tank, I already had a clown,blue, yellow and sailfin tang also a queen and emperor angelfish. The clown tang is pretty small but terrorizing the pbt and the yellow is attacking the purple tang, the queen angel got in on the action now and is nipping at the powder blue. I can see small lacerations on the yellow and on the powder blues fin. Theres 400 pounds of live rock covered in algae in there also I let it grow on the back wall so there's plenty of grazing room, it's an 8 foot tank. I've tried moving the rock around no luck. What can I do?

I would get those breeder nets and put everyone in their own. Let them sit in there for like a week or so then let them out at the same time with lights out. That's what I'd try anyways

Separation during a week long acclimation where they can see each other and interact, through a protective barrier.
