Two of my first fish were a standard JD and a widebar dat. I named them Bad Cop and Good Cop respectively, because the JD would mess with the smaller/more delicate fish and the dat would regularly step in and regulate things without being aggressive to the smaller fish.
Obviously a 6''+ widebar isn't cheap, but my point is that sometimes fish just have the right personality to do this.
