AFAIK, Yes. The only relatively "peaceful" Africans I been told are Electric Yellow Cichlid (Labidochromis caeruleus and Acei Cichlid (Pseudotropheus sp. ). There may be others. They still need a bigger tank.
But you are starting with VERY aggressive fish. As soon as they get some size on them they will fight. And they cannot grow well in such a small tank. They will still fight and be stunted before they pass away.
A. Return the fish. Ask here for suitable fish for a 20g or go to a non-chain fish store.
Or
B. Get a much larger tank. Add most peaceful first, add in yours last.
C. Africans need very hard water. Aragonite or crushed coral can help keep your water chem where it should be. Or there are substrates sold for Africans.
The only Africans that can live in your tank would be some of the dwarf Shell Dwellers Not as colorful, but still cool.
Right now you have a disaster waiting to happen IMHO
