That snake is in SERIOUS need of a few soakings and a tub. Get rid of that enclosure completely unless you have another species to put in it.

Put it in a tub. provide two hides, one on the cool side, one on the warm side. Use newspaper for the substrate. get a digital thermostat. the warm side should be around 90 (using an under tank heater) and the cool side around 80. Put a big water bowl in the tub to keep humidity high for a while. Don't bother trying to feed it at all until that shed clears up.

2 times a day put it in a small Tupperware container with about a half of an inch of 85 degree water for 30 minutes.

Hang in there. just read, and listen to what you read. we will help you get it right!
