Hello, I am back.

To begin, I have posted before about this snake and here is the link to the last Thread.

I wasn't sure if I was supposed to begin a new thread or not but I am so here we go. I have a 6 qt tub, back and sides obscured, it has a small water dish and one hide on the warm side. The warm side is created using a UTH that is regulated by a thermostat. The thermostat is set to 87 degrees F and bounces between 84.9-88. Aspen bedding and the humidity hovers at between 60-70%. Following the advice I received in the last thread, (again, thank you for your patience), I left him to himself as much as possible excluding changing water. His weight is now 58 grams which is horrifying. I attempted to feed him a f/t mouse that had been warmed and puppeted. No luck.
Seeing as he had more interest in trying to leaving the box then eat the mouse, I eventually left the mouse and decided to check later. As I went to remove the mouse from the box I noticed the cool side bedding was actually fairly damp and must have been spilled at some point. (I am sorry your bedding was so cold over there, tiny noodle.) The bedding on the warm side was dry.

Since it has become clear that he was not eating regularly when I got him, I will try to get him started using live prey, which I will need to leave town to get. (Hoppers, yes?) Would it be okay for me to assist feed him a smaller item so that when an additional week has passed, he will have the strength to eat it?

Additionally, he has these soft white callous like marks on the sides of his head that remind me of skin that has been around water too long. It isn't mites, they don't move. Thoughts?
