Problem #1I house my balls communally in a very large tank with felt substrate
Problem #2in feeding box
Not the best idea when it comes to live.leaving live or frozen in with him in tank alone overnight
Your perception, BP are not communal animals and what I see is anthropomorphismthey are happy as they could be
I have not read the rest (paragraphs would help making it easier to read) but anyway because it has worked for the others until now that does not mean it works with this one, obviously it's not.
Not sure why you would house snake together, especially housing a new acquisition with ZERO quarantine but it looks like you have a lot to brush up on.
