Looks like he is now in blue. With such a light color snake, its tough to determine pre-shed. No wonder he was hissing yesterday. Poor little guy.

I will be getting him a hide, as suggested. Thank you

I took an old plastic container with lid and cut a hole in the lid. Also put some moist substrate in there. Put that into his tub. Incase he wants to use it to help him shed. Plus, it will increase overall humidity in his bin.

Am I missing anything else?
