African Cichlid Compatibility (Ps. Socolofi)

hi,

I have a 125-gallon aquarium (currently in the nitrite spike phase of
fishless cycle process) which I plan to stock with the following once the
tank has been completely cycled:

6 Yellow labs
6 Acei
6 Socolofi
1-2 Synodontis Eupterus

Will the Ps. Socolofi too aggressive for this mix?
I have read that a sole Ps. Socolofi in a mbuna community tank may become a
bullying tyrant, but will six Socolofi diffuse the aggression or only make
it worse (for the Acei & Labs)?
