I believe its called treasure?
At a glance I thought it was a Boa constrictor, with a slightly odd shaped and coloured pattern, which with all the morphs being bred these days, wouldn't be unusual. Boa's tend to be a favourite with large snake keepers, as they are very placid, and grow to around 8 feet.
But looking more closely at its eyes, that's a reticulated python, Boa's have dark coloured eyes, and usually have a "bar" running horizontally through. Retics have orange coloured eyes.
They are the most aggressive of the large snakes. And can grow up to 30 feet in length but rarely do in captivity.
Its a nice healthy looking one, you can tell be the iridescence in its skin, when the light catches it.
