Yeah, the bigger the better. I have a 2 year old iguana, and she has gone through a 10 gallon tank (when she was about 7 inches) to a 50 gallon tank, and finally to one that is about the size of a large upright piano. She spends most of here time on top of it though, lol. I plan on making here one as big as I can, mabey half a room, as soon as I get a bigger house. This is a great website for reading about Iggies---->

Lots of pictures of his pets. Great pics from month 1, to full grown, great habitat pics, and indepth food talk to. Check it out, and good luck. Iguans are an awsome pet, they are like having a dianasour in your house. They do take MUCH care, a large voriety of food, constant handelling to make them calm, and you must always remember that they still are a wild animal.
With that said, if you are the kind of person to get overly consumed with your pets, and gives them averything then need and want, you will make a great iguana owner! Good luck with your decision.
