Yup, it is a hybrid based off Xiphophorus variatus, a fish that occurs just a little north of platys (X maculatus), in Mexico. In many ways, they are halfway between swordtails and platys, however, most of the ones in the hobby are hybrids.
It's a great, undervalued fish. I had one become so tame it would swim into my cupped hand when I was doing weekly water changes.
It needs a higher pH 7.5+, hard water and a temperature range of 20c to 25c. It's a fine community fish.
