Sometimes mine does that as well,half lower end body in the hide and from her head down a few inches on top the water bowl.. Every couple days he does it for a few mins here n there..other words he is always in his hide..also common sense says to me to have the heat mat on thermostats and have the probe tapped to the out side of the pad on the bottom and then get a thermostat for the inside and place that probe under the bedding in the middle of where the heat pad is,use some alminum tape to hold the prob to the bottom of the tank.. That's how have mine set up
