Your male looks like an extended red, his branching is a bit excessive, so it would be a good idea to use a more moderately finned female so you don't end up with rosetails. You should read this article on rosetail characteristics and the extreme expression of the rosetail trait: http://www.bettaterritory.nl/BT-AABRosetails.htm
The problem with breeding a marble to an extended red male would be the introduction of the blonde (cambodian) gene--this will wash out the red color and it won't be as intense. If the female happens to have the red loss gene, which can look like marbling, you might get some really ugly babies. Sometimes they turn cellophane, and sometimes they turn to a weird brown color.
As for making platinum reds, which is what I think you're going for, I believe you would get the best results from a red based copper gold or platinum female. I wouldn't skimp on the quality of the female either, since you'd probably have to breed back to mom in order to get more metallic in the babies.
