So, you clearly have a mix of African and South American cichlids. Which you will really want to sort out. The mbuna will be much more aggressive than the South Americans in the long run. Mostly because you are likely to have much more spawning. These fish will readily hybridize with each other and I wouldn't be surprised if they are already hybrids. Cichlids in spawning are actually kind of jerks. In the long run, if you really like the rope fish and the peacock, I'd suggest keeping the two of them, getting rid of the cichlids that you have and trying to find some large bodied schooling fish.
Additionally, I'm more concerned about your tank maintenance and the lack of cycling. Have you tested the water at all and how often do you do water changes?
