In my tank, USUALLY, when a fight starts, other fish come get in the middle of it, or attack one of the ones fighting. Pretty sure they all want to make sure that no one fish gets too dominant, so they get involved in every fight, which pretty much makes them stop fighting.
Only time I have a problem is when one fish, for whatever reason, becomes the true undisputed top of the pecking order, and starts chasing EVERY fish in the tank. I just removed a Zonatus that got like that. I'll maybe try and re-introduce him back into the tank in a couple weeks and see how it goes.
I had a Breidhori that kept the Zonatus in check, but he got sick and died on me. Ruined the whole balance of power in the tank.
