Walter, I doubt that the Rams would breed in the same tank with A. cacatuoides unless it was very, very large > 8 feet long. Males of highly polygamous species like A. cacatuoides have been reported to defend tanks over 2 meters long. Rams really don't like a lot of disturbances when breeding or they will eat their eggs/fry. Being smaller than male cacatuoides, and much less aggressive they wouldn't do very well and definitely be out competed in every way. I'd try A. cacatuoides with a dwarf Laetacara or maybe Bolivian Rams.
