If you plan on getting a rescue think again, people re-home them / get rid of them for a reason.
I used to do iguana rescue and trust me it's no walk in the park.
The puppy dog tame one you see are exceptions and even then do not believe they are always puppy dog tame iguanas have nasty bites and tail whipping is no better, I had scars for years.
Now if you really want one get a baby from a breeder and as for your enclosure it will need to be bigger.
