Right now I have a 20gallon long terrarium with screen top that flips up from the middle. he's only 5 inches long right now. I will definitely upgrade to a much larger tank when he gets a little bigger. I have a temp gun and a thermometer with a probe. basking spot is just about 110 average, hot side is is 90-95, and cool side is 80. so not really looking for so much heat, just light. maybe I will try a household light. what do you think, a 60watt maybe?
