I use an under the tank heating mat. I use both a digital prob for double-checking spots and a cheap thermometer that's used in quick glances on especially cold mornings since I have the joy of living in Maine.
I already put him on paper towels after I finished cleaning the tank tonight. Tomorrow morning I'll be driving to the pharmacy to pick up some recommended antibiotic creams and giving him a warm bath before I go in for work.
I'll be giving the tank and hides a diluted bleaching on Sunday. Monday will see a vet visit come Hell or increased visit prices. I've caught the rot before it's started to flake, so can I hope that as long as I'm diligent in treatment and avoiding moisture build-up in the hides (I'm positive this stems from his constant tipping of the water bowl, DAMN IT SNAKE), this problem can be solved and avoided from now on?
And thanks for being on at one in the morning, Kaorte.
