Any idea what this thing should eventually be paired with?

I found this guy at PetSmart a little over a month ago. At first, I thought perhaps it might having something genetic going on with the clear belly and spotted nose. But of course, it's from a pet store, there's not guarantee in anything.

Onto the topic at hand. He's currently unsexed, but regardless, what should I pair it with in the future?

He's also got some white starting to develop on the start of his neck stripe. Unfortunately my better camera isn't currently with me, so the colors are a little off.
