In the future you may have some major aggression issues with the johannies and the auratus. With super aggressive species like the Melanochromis you should have only 1 species per tank, same with Metriclima species and other aggressive types.

The Mel species and Met species of malawis are the trouble makers of the mbuna. I keep kenyi which are some highly aggressive mbuna they can cause some serious trouble at times.

Trust me shouting at a mean cichlid makes no difference.
