Going to shed or something else?

If it was sold to you as Colombian BCI, that's most likely what it is, but you won't know for sure without knowing its heritage.

I bought him from a very distasteful breeder so I wasn't sure, thanks!

EDIT: Backwater reptiles before I knew anything about them. I love my boa, but I hate backwater. I was mostly confused because I bought a "common boa" and then they sent me an email saying "we upgraded you to a BCI Columbian". So it's been kind of in the air since I got him back in 2013.
