Hi, I am new to the forums. I started taking care of Regis, an adult BP, a few months ago. He is a very good snake, but I am worried about my setup for him. I was given Regis when his owner had to move out of his house to live with a friend, and he didn't have space for him. I have a 10-gallon tank for him that I fear is far too small but in a couple of weeks a friend is giving me a 20-gallon for him. He is on newspaper substrate with a hide that I made out of a cardboard box. He has a water bowl large enough to fit in, but he spends most of his time either inside the hide or basking on top of it. It stays about 79-82 degrees inside the tank because of an adjustable red heat lamp that I keep on during the day and turn off at night or when he retreats into his hide.
Unfortunately, I was given Regis at short notice and I have never really known the proper way to care for him. Caresheets and books help, but they offer conflicting advice and the changes they tell me to make often seem to stress Regis out.

Regis has not eaten in months. I have tried everything that I have read, including getting him mice of different colors, gerbils, live mice, and placing the (dead) mouse in his hide with him and covering the entrance for a while. I have tried re-freezing frozen mice to make their scent more pungent. He sniffs the mice and looks as though he will strike for a moment and then ignores them. I am very worried about him. There is not a vet in my area who treats reptiles.

I am sorry that my post is so long-winded, but I would really appreciate any advice that long-term BP owners could give me. I just want Regis to be happy and healthy.

Thanks!
Katie.
