swordtail guppy

[wentzville]

I was buying feeder fish for my bluegill and when I looked in the bag I noticed a long point on the bottom of one of the guppies. I'm talking long. Swordtail long. I put it in my QT tank for now to check it out. After 2 days of looking at it, it is a swordtail guppy. I've never heard of a swordtail guppy. Can I breed it with another guppy or platty or is this something that can't breed. It looks like a female guppy with a male length sword.
It also has a molly like white with black spot color. Very cool looking.
I would like to breed this but with what?

Maybe a hybrid already? If it is a guppy it will breed with any other guppies. Any chance of a pic?
