Guppy? Endler? Other? Help...!

[Tfatk]

So a few months ago I went to a local fish store to pick out a guppy. They had a nice variety of colors and patterns on males, so i bought one, but didnt notice a tiny "guppy" fry that came along in the bag. A few months later... he's not matching the shape, size, or colors available

I have him in a 10g along with some neon tetras, but what i cant understand is... how is a guppy smaller and thinner than a neon?

(Tough to tell)
But ive never seen a pattern like this on a guppy. Id like to know possibly: Which of the 2? And what kind because of his size?

its a wild-type guppy or endler cross, all male wild Guppies and endlers are smaller then the normal male Guppies

It looks like a wildtype guppy. For sure no endler...! To me that's certain...
He doesn't show any endler traits.

Hello and welcome to the forum. When it comes to guppies and most live bearers @emeraldking is pretty much the expert here. Nice looking tank, I like the driftwood.
