Habitat, Tank Conditions & Setup

One end of the tank should have heating equipment, and the other side should be left cool and a few degrees cooler than the warm side. A thermometer should be placed on both sides of the tank so that it can be effectively monitored. The temperature should be between 80°F to 88°F. The cooler side should be between 68°F to 72°F. Humidity should be maintained between 60% to 80%.
