In your reptile enclosure it will be crucial that you have a UVB light, which can be turned on for an hour or two each day. Make sure there is both light and shade so the iguana can go back and forth. Adult iguanas can become aggressive and territorial when they reach sexual maturity. It is also important to remember the baby iguana that you buy at the pet store that starts out at six inches can grow to be four to six feet in length at adulthood. An iguana also needs water.
Water is needed for the normal functioning of every cell in the body of the reptile.
Iguanas do not drink from a pool or dish of water like normal animals. Instead, they lap up water from the sides of the enclosure and from rocks. So it is important to mist the aquarium two to three times a day. This will also create a humid environment for these animals, which keeps the skin of the iguana from drying out. Most people can agree on the idea that iguanas are vegetarians.
