Hi,
Actually I thought I read Amir used to run a pet shop but had recently sold it?
I know I usually get these thigns wrong but wasn't it called sunset pythons? Or was that someone else.
My recommendation to send the pictures to Amir stands - I know there are some subtle yellowbellies but that seems a bit too subtle for me, personally, not to want confirmation from a third party not the person I bought it from.
As I said he doesn't need to be intentionally lying to you to be wrong about whether it is a yellowbelly or not.
Either way when you breed it to your ivory you will find out. Be a bit late to complain but you will find out one way or another.
