There might not be a better choice than a real RED German Red:
That looks more like a Ruby Red to me.
Some quick googling (I know nothing about peacocks) indicates that ruby reds have more blue spots/spangles throughout the body and their faces are not as blue. Whereas German Reds have more solid blue faces and more solid red bodies.
That said, I think it's somewhat a personal preference or marketing decision as to what you call it, since to the best of my knowledge no one knows for sure if German Reds are line breds or hybrids or whatever. Regardless, they are pretty fish and I don't really care their origin from an aesthetic perspective. Especially in an all male show tank (which I assume this is), the breeding question is moot.
