I have an update!!
And a good one I believe ^-^
I've been monitoring my BRB very carefully for the past few days and he is starting to settle in and show normal behaviors again. I think he is happy that I've left him alone! I've seen him out and exploring and on his hot spot and in the cool spots and burrowed underneath some sphagnum moss. There is condensation on the sides of his enclosure so yay for humidity and Temps! The popping noise when he was breathing is gone and I'm replacing his water with fresh clean water every day. Today he struck at me and I was happy! He is showing some normal defensiveness like my KSB woo! His scales are looking vibrant and shiny, and he seems more relaxed. Hopefully everything will stay this way, I know things can happen fast but I am hopeful.
