The Heating Technique
Iguanas should be maintained warm so that proper digestion of their food will be allowed. This technique will also save them from diseases. A good type of thermometer must be placed inside the tank so as to monitor the temperature of the house.
There should be a basking spot that has a temperature of between 95-100 degrees F. One of the best heat sources that you can opt for is a spotlight. Other options include the undertank heaters, heat tape, or ceramic lights. Some recovering iguanas will need warmer temperatures especially at night.
The Feeding Scheme
It is important to be very careful with the food that you feed your iguanas. The green iguanas are plant-eaters. Any kind of animal protein should not be feed to them. They may like the pizza and junk food treats but these food will do them no good and will henceforth subject them to kidney failures. Vegetables must be given to them in minimal quantities. Spinach is a NO NO to them.
The diet required for iguanas are the food that contain high content of calcium, vitamin D3, and low in phosphorous. The commercial iguana food can also be made part of their diet.
