the cage can be furnished as you please. As can the setup for heating. Heating will depend on the setup, heat mats can be used under, or lights/che/rhp can be used for a raised basking spot. Humidity may be a problem in an aquarium but that can be solved. The good thing about a large tank is that there is more space to create a temperature gradient. In this case you could even play around with temp ranges and find a gradient that works better than the cookie cutter temp ranges given in caresheets.
