hmmm they might get a bit aggressive since they could breed, but we keep a whole range of fish with out auratus's other mbuna and haplochromis, greshaki, scofoli, giraffe's, dolphins, textilus, estharae, peacocks and a hoplo
They should be fine wif most africans that are bigger then them... i found they tend to kill anything smaller unless the tanks has heaps of hiding places and is quite heavily stocked.
