I would say some Cichlids are more agressive than SH's.
I have a 9" Mannie "Jaguar Cichlid" in with my 14" African SH and the Cichlids are definitly the more aggressive, My Jag 'Spot' as I call him is even territorial towards me when I go near the tank. He bites me when I put my arm in his corner as well.
I also have a Convict of about 2-3" in a floating container in the same tank that rears up at anything, SN or otherwise regardless of size.
I have seen a picture of a Mannie skull and there are plenty of teeth.
