I have been looking on Craigslist for an Iguana to Rescue. I found one that has been housed in a tank that is the same size as he is? (All Most) WTF is wrong with people? So I was wondering if it’s better to build an enclosure or I have also found a tank that may work in is 6' L X 3’ T X 30" W. From what the owner of the tank said He had his 5' Iguana in it for five years. I am also do my research on Iguanas so may be I'll find the answer I'm looking for.
