This obviously only applies to community tanks obviously, but the question is. Who is the fish in your predatory/large fish community that always seems to jump in and break up any fights before they go too far? What species is that fish? Is it the alpha of the tank? Pictures or videos of the fish in action? Experiences and observations of this fish's temperment? Do you have a fish that rarely ever starts fights but always is the one to end them? Would love to hear your experiences and see your fish in action.
