Hi ,, a better ? is how much time and money do u have to spend.. I own 2 iguanas one is a 4 ft 2 in female about 5yrs old,she was adopted,, and the other is a 10 month old 27 in male .
The encloser for the female is 7 feet long x 6 feet high x 4 feet deep,, the male is housed sep.. 5x4x2 for now.
They are great to have but just like some types of fish ,do your research before you buy,,or better yet ADOPT. They have special needs in diet, lighting,,heat,,differant temps at diff. times and places in the encloser,,, lots to learn. some sites herp center.com iguana zone .com
