umm lets see a captive bred snake, vrs a animal that we as humans have NEVER seen, in person, full grown, ever. yea good comparison there. Also did he keep it at the same pressure? The Coelacanth for example can not survive in shallow waters. It has to have the high pressure of the depths to survive. Snakes have been bred in captivity for eons. Maybe not as long as say your family dog. Just like any animal you need to know what your caring for and its requirements. I wouldn't suggest a iguana to someone who is not prepared to make fresh high quality iguana salads for it every day and keep a enclosure large enough for it to be happy. Same as you wouldn't recommend a Irish wolf hound to someone that lives in a studio apt.
Well that humidity seems fine almost a little low, but... When you sprayed the enclosure the humidity level may have gotten too high. Also how big was the snake and what size of food was offered. Was it live or pre-killed? What size enclosure was the snake in? Also whats the cold end?
