What's the worst fish fight you have ever witnessed?

My dads old Blackbelt vs literally everything else in the tank at the time which was a smaller male jag,Midevil, male convict and my male Dempsey who I still have.he was on once side fighting the Midevil when everybody else decided they wanted to join. He backed up flared out completely and startled snapping at anything that got to close.killed the convict, next day no one went near it.
