Yup, what they said. No iggy should be in a tank, especially not an adult. These guys are climbers and need lots of height in their enclosure. If you live in a mostly sunny and warm area, such as Texas or that area, you can do what I did for mine and built a wood framed wire cage to give them the air flow and warmth outside (except in winter of course, then the cage comes in). Otherwise, look into a nice enclosure that will give the big guy plenty of climbing and romping room. Id say a good 8'x6'x6' would be nice.
