I would feed in the enclosure ur more like to get tagged moving it to feed it. then feed it. then moving it back.

Also put it in and leave it be for a week. You holding it after you just got it can lead to many more probs best to just leave it be for a bit

also you said u got a heating pad? like a human heating pad or a under tank heater? or what? Also is it hooked to a thermostat?
