If you want healthy Cichlids, fishless cycle your tank.
I would focus on one type of dwarf cichlid if I were you. Or I would not get the Rams with the kribs and acaras as they will get bullied. You could pull it off if you make plenty of rock hiding places like stacking a background of slate rock. I would start out with 4 kribs and 2 flag acaras. Or I would Get a pair of Gold Rams, German Blue Rams, Bolivian Rams, And Ruby Rams. whatever you do make a large number of hiding places and don't cycle your tank with fish.
