There appears to be plenty of different crosses that have taken place with "parrot" fish in Taiwan & elsewhere over the years, but the origin of the Blood Parrot is a rather simple cross, of two pure fish. There have been first generation examples shown of this cross in the hybrid section. Some of the strains with normal mouths, such as the Red Mammon shown in the photo, are quite beautiful fish IMO.
