There are no dwarf versions of this species so you must understand from the very start that green iguanas by nature can grow really large. You cannot by all means make an iguana a dwarf version not unless you expose it to severe chronic malnutrition and then to continuous hypothermia.
Of course, when you do safe keep it on a tank that measures only up to ten gallons, its normal growth will be hideously hindered. Such kind of environment will also make the iguana sick and crazy to the highest level. If you are really serious in making the iguana appear small, then kill it slowly. Killing it slowly means keeping it in a very small-spaced tank container, giving it dull food to feed on, and then exposing it to extreme cold. You may likewise try to be humane and just simply buy a stuffed toy iguana.
The iguanas are naturally from the exotic tropical areas so when they are taken in as pets they must be fully maintained. Meaning, they must be catered with sufficient and healthy food, homey housing environment, proper lighting, and utmost tender love and care.
In the absence of any of these factors, they can be subject to premature death. It is a must that you know for a fact if you will love to take care of a giant green iguana before purchasing one. They get extremely huge and live a span of twelve to fifteen years.
