Two things I have found different with Vics than Malawi is the males don't always color up at all with no females present. My Astatotilapia latifasciata is an exception.
And the ones I like (like Pundamilia, not sure if this applies more broadly) are either on the aggressive side (so you would not want to mix with a timid fish like certain aulonocara) or so timid (like Ruby Green or Christmas Fulu) they thrive in a species tank, away from all those scary Malawi.
I have a single male P. nyeri in with comparably sized and larger peacocks, haps and mbuna in a heavily stocked 125. He holds his own and is actually more on the aggressive side compared to the rest of the tank.
These guys get horribly aggressive in the presence of females. I could imagine things being bad if you tried to put them as one of a few (Malawi) breeding groups in a tank.
