Spakey's cage one side arid with a heater under the tank on the left bellies need to be kept warm. Other side moist which aids in sheading (they eat shead). We spray the tank when it is dry. Moist area has reptile moss on the reptile carpet. Sand is not recommened for African Fat -Tails. No lights are needed unless your room temp is below 68. Two thermometers are in tank for the arid/moist sides and a hydrometer.
