You should really invest in a temp gun to keep track of your temperatures. I used to use a ceramic heat emitter and a UTH also. I never realized just how hot those ceramic heat emitters get until I used a temp gun on one of them. It was way to hot! Your snake may just be to warm due to the UTH and ceramic heat emitter being to hot. What kind of thermosat are you using for the heat sources? I no longer keep my snake in a tank due to the incosistencies of the heat sources. I just find a tub to work much easier for myself and my snake.
