If you want something that looks like an iguana maybe you should try an austrailian water dragon OR a chinese water dragon. If you are a beginer dont start with an iguana, get something simple. a water dragon is pretty nice looking.
If you really want a species of iguana then get a fuji iguana lol they cost around 2500 quid :shock: and dont grow that big. Or get a desert iguana they grow real small about 12 inches and are really tame also they are cheaper - much cheaper.
but i find them boring... conpaid to something like a water dragon me personal i had a water dragon and they are really nice... much more active then a desert iguana witch i have also had. Now i have my 3 foot iguana who is really nice and much more intresting.
