Normally more than one cichlid species in an aquarium is not a good idea, but here you do have space (I will assume the tank length is five feet at least, maybe six?) so this could work with an aquascape well divided (by chunks of wood on the substrate, plants, branches) and depending upon species. Some Apistogramma are harem species, others better in pairs. Females can be very rough on other species (Apistogramma) during egg/fry guarding, I have had them kill each other and that was in a 4-foot 70g tank. Agree with essjay that if you want to raise fry, do not have substrate fish that are nocturnal like Corydoras. But aside from saving eggs/fry, no issues generally as the cories will bumble around and get pushed and head-bunted but normally not with injury.
Also agree with Colin that both rams should live more than two years; the normal lifespan for both is 4-5 years. My Bolivian Ram male on his own (meaning no other cichlids, just over a hundred characins and Corydoras) liveed into his ninth year. The common blue ram (in any of its varieties) needs warmth, no lower than 80F (27C) or it willnot live beyond 1-2 years. The Bolivian is not so demanding of warmth. All of these are sensitive and somewhat delicatee fish, requiring stable water conditions and parameters.
