Pterophyllum scalare, P. leopoldi, P. dumerilii and P. altum are the wilds recognized as separate species I think.
Phenotypes (looks different) are what you are talking about and yes all will pair and mate with each other. Just like with dogs and other animals angelfish are selectively bred for the desired traits we want but yes all healthy critters want to reproduce (nature).
