Are Hermit Crabs self temp regulating? I know that lizards aren't and they will sleep in a too hot spot until they literally cook themselves! Do crabs know when to move away from heat if it is too warm for them? The reason I asked is I have a side mounted Heating pad and 2 of the 6 new crabs have half buried themselves over there, I am sure they are just destressing, we have had them less than a week. They are right up against the glass where the heater is I don't want them to cook! My tank temp and humidity has been fairly stable so I am sure the tank conditions are good, Humidity fluxuates between 70-75 ish and temp is about the same. I do think that one of the new ones is down for a molt he has been down for 2 days but the others just dig a little hole and lay in it and walk around at night to eat soak and drink.
