Okay, wow, it is hard finding a guppy that looks like my guppy's!
This is what the orange one looks like, only he doesn't look ashy, he is more viberantly white!


Okay, this is the best one I could find. Take all the black off the tail, and all the different flecks of color off the white part, and you basically have the bluish guppy!

I hope that this helps!-
