To break down what hypo motley means:
Hypo or Hypomelanistic is a genetic trait that ends up with less black/dark-brown pigment (melanin) being produced. A normal corn snake would have the same colour with darker red and black lines around the red parts.
Motley is a gene that give the corn snake a distinct pattern. The belly has no check board patter, a trait a regular corn would have (this is why we asked for belly pictures), motley makes the pattern on the back to have a row of spots of light colour on the darker colour rather then a saddle pattern of dark on light. You see how the pattern on his back on the front half is different from the back? most corns have the pattern of his back half all the way from there head, the spot pattern is what they call motley.
This means you have a fancy corn snake. :cheers:
One guy speculated that it might be an amel or Amelanistic. An amel is a corn snake with no black and would have red eyes (this is why we asked for pictures of it's eyes), hypo is kind of a half ways between normal and amel. Amel is probably the most common morph aside from normal, Hypo is less common and ends up being more expensive, nice find!
