Yeah, it's a rear fanged colubrid. Meaning a bite would probly give you a headache and swelling. Similiar to a bee sting.

This is based on what I know about other rear-fanged colubrids such as vine snakes and mangroves. I'm not sure about this particular species though.

If it were me, I'd buy it. Other wise it'll end up with someone who knows nothing about them at all. They're a little known species.
