Congratulations! I wanna see pics!

I have 6 iguanas; 5 free roam (they have their own room) and 1 yearling in a reptarium (which I do not recommend - hard to keep humid and they can rub the scales off their noses against the mesh if they're stressed).

I highly recommend reading Melissa Kaplan's site if you haven't already. She has excellent info from diet, to housing, to health issues. Here's some links for you:

Melissa Kaplan's Green Iguana Care Collection (the links to the iguana pages are down the page on the left side under "Page Index".)

Reptile Housing: Size, Dimension and Lifestyle (Determining enclosure size)

Vegetable and Fruit Names: A Multi-Lingual Glossary for Herbivorous and Omnivorous Reptile Keepers (List of good and "bad" veggies)

I have written up a lot of advice/info on keeping iguanas over time as people have asked me. I don't have it in caresheet format, but I'll be glad to send you what I have if you'd like. Or if you have specific questions or concerns, hit me up anytime.

The most important things you should know off the bat -
UVB is absolutely necessary for calcium absorption and a must have
Humidity/fresh drinking water at all times/regular baths
Night temps no lower than 60 degrees F, optimal day time temps in the mid 80's F
Vegetarians- no bugs or mice
No spinach, broccoli or lettuce on a regular basis (only as treats)

If you'd like to see pics of mine, they're all in my webshots gallery.
