Tang Gang Wars

[Zoaelite]

I have the weirdest thing going on in my tank right now, I have acquired my final tang (A beautiful Yellow Fin Tang) which brings me to 7, after 2 days of my vlamingi beating the crap out of him and forcing him into the corner I now have gang wars going on .

My Pyrofurus Mimic, Yellowfin, Ring tail and Purple tang all seem to be good and hang out in one area of my tank but every so often the Two spot Bristletooth and the vlamingi will dive bomb the group, attack the Yellowfin only to get attacked by everyone else. I have watched this happen like 13 times now, its starting to get a little funny (Everyone is looking in good shape though). My yellow tang is oblivious to everything that's going on.

Anyone have there tangs do crazy stuff like this?
