actually in his last shed about a month ago, he had a bit left in his nostril but i managed to get it out soon after. its totally a possibility that there was a bit left though, thanks for helping me remember that haha
his tank is 80 on the cool side, 86 on the warm side and basking spot is about 90. after inspecting him i upped the thermostat 2 degrees with the same idea in mind.
really hoping it is just a bit of shed or dirt in there. also thanks for the link!
