Hello,
You will need to start treating for impaction right now. Go ahead & get some sugar free applesauce, canned pumpkin & squash babyfood along with a couple of drops of olive or mineral oil in with the mixture. Do NOT give any feeders or solid foods right now, especially if he is impacted. Get a plastic dropper or plastic syringe to get the food mixture into him, carefully by dropping it on the end of the nose.
As directed, begin giving a warm
bath & massage the belly starting at the armpit all of the way down to the vent area, on the right side.
Do remove the walnut shell substrate & replace that with paper towels right now, it is much safer.
What are you using to measure the temperatures with? A stick on type of thermometer, a digital probe or a temp gun? The basking should be 95-105 for that sized tank & on the cooler end around 78-82 or so, roughly.
The ambient temperatures of the tank should be no higher than 80 or he will over heat.
What type of basking light do you use?
