I think you are more stressed then the snake Just relax and let him get use to his enviroment.

My RTB wedged himself up along the lid to his cage for the first several days. Weard behavior compared to now. I left him alone for a good week, only changing the water and he finally moved down and burried himself in the substrate. He likes to lay and just poke his head out now waiting on a F/T fuzzy to just show up at the end of some magic metal tongs.
Now he likes to read this forum with me a few times per week. yours will settle in and be a good pet. Can't wait to see yours...
