I'll probably go with 4 rays, since I have yet to see a 6 ray. lol
I'm thinking that I'll go with the marble gene. Since I thought that he was a blue dragon at first, I might try to add that into it. I could try for a marble that is a butterfly as well, since that gene/color scheme will be carried on, most likely.
Since I like his color, I think I might stick with the whole blue/green with the red underneath. I like it.
And, question, what do you think about this girl for breeding purposes? I can't see if she's got 2 rays or 4, but I believe that she might be a delta.
