I just have a space heater on 9on the table my terraium is on. the tank stays ebetween 70 and 80 degress the whole time. Not to mention since the heat stays up so does the mumidity. Two birds with one stone I have mine ina 10 gallon terrarium I sloped the subsrate toward her burrow. She seems nervoius all time only when light come on and when I accidentaly bump thr table she is on. OTherwise she eats like a pig and stays in her burrow most of the time. I am thinking about getting a 5 gallon terrarium to pout her in next time.
