I'm sure this isn't the first time you've been told this, but your stock list is all wrong for any semblance of success with this tank.
You either need to keep one of each species and go all male, or choose less species to keep and form breeding groups out of those species.
If you go all male, you won't want any species that closely resemble each other, or two males of one species.
If you go with breeding groups, I would pick 6 species that aren't likely to crossbreed, and keep them in large enough groups to disperse aggression amongst them.
As you have it now, everyone is just going to try to breed with everyone else. There are no real "lines" drawn.
Once the frontosa matures, you will likely find you're missing a few mbuna, anyway, so I would decide whether I wanted fronts or Malawi cichlids. (They don't have the same dietary needs, and problems will arise as they grow up.)
Your fish are maturing, and odds are that it will only get worse in the tank as they do.
