Old world and new world Cichlids don't get along to well. Parrots have deformed mouths to where they can't fight back with mbuna. Old worlds are hyper aggressive and should only be stocked with old worlds. Here is an article to help about stocking.
Whats your tank test?
What's the temp.?
Make a lot of surface movement by aiming power heads or canister filter out tube up. Or buy lowering the water so a hob
filter will splash a little and make movement.
The heavy breathing is more than likely if not water perimeters stress from one another.
