I recently acquired a Pacific Ring Tailed snake in my wouldn't be the first time. But I want to keep it i'm just not sure what would be the most humane way of taking care of it. If anyone had any links or advice with them I'd love to hear it. Right now it's chilling in a 10 gallon fish tank. For the most part it's docile and not very aggressive at all. Super pretty snake I just want to know how to take good care of it. I think it's a adult it's about a foot long and a little thicker than the other ring tailed snakes I've seen on my property.

Any help or advice would be appreciated. I live in northern California about 2 or 3 hours north of San Francisco if that helps.

Thank you in advance
