He's probably het albino Boa Imperator (BI). In other words, a normal BI, het albino and maybe jungle. Nice speckling and nice head spear.

What was he being fed? Do you have F/T of that available?

What are your temps and humidity?

Is that a temp probe or thermostat probe in the enclosure?

He's pretty small so you want to be sure to get him started properly.
