> I was thinking about a lizard. I have owned and hatched anoles and those wild gekos that live on the front porch.
On your front porch? Do you live in one of those nice, warm states that ig owners would give anything to move to? 
> well anyway i was thinking about an Iguana? what type is best for your first Iguana?
There are a couple of kinds of iguanas, and Green Iguanas are the biggest of them all. I would not recommend it as a beginner herp, (although looks like you've got experience) and have heard from many desert/rock/cuban/cteno iguana owners that their igs are smaller, sweeter, and more interesting than Greens. By the way, I don't know if those names I just listed are accurate- head over to the desert ig or cteno forum for info on non-green igs. Green igs are total herbivores, some other igs are omnivores. In my opinion, it's probably easier to buy good prey to feed an omnivore than it is to find the right mix of veggies, fruits, and greens for a green ig!
If you decide to get an iguana, I strongly recommend that you adopt one from a shelter such as the Mid Atlantic Reptile Society (MARS), or your local equivalent, depending on where you are. You can find links to all sorts of rescues on Melissa Kaplan's webpage, http://www.anapsid.org.
When you rescue, not only do you give a second chance to an abandonded ig, you get to actually PICK whether you get a boy or a girl (each come with their own set of problems), sweet or feisty, long or short spikes, and green, grey, red, or brown... something most of us just have to wait to find out.
> How old r they b4 u can breed them.
I would agree with the previous post that it would be irresponsible to breed green iguanas. They are one of the top dumped herps in the US. There is a glut of them everywhere (petstores, rescues, overseas breeding mills), and NOBODY wants these guys. I'm glad to meet someone who might!
>do they fight?
YES. Viciously. They'll kill each other or other herps, and many of us have the stitches to prove that they'll bite humans, too; especially during mating season. Not only does mating produce iguanas nobody wants, it can mean serious injury to your male and female. Ig mating is violent.
>how big do they get?
Six feet or longer, 15 pounds or heavier. The body:tail proportion is something like the body length of a small terrier dog with a tail as long as your leg. Well, maybe my leg. I'm not very tall.
>I have a friend who has a 2 foot long Iguana he got 2 yrs ago when it was a hatchling. I'm just looking for some info
Has your friend's ig gone into breeding season yet? Before you decide to get an ig, you might want to witness how crazy, mean, and neurotic it is possible for them to become. Then again, you probably are thinking about getting one because you've also seen how sweet, intelligent and beautiful they can be.
Good luck! Drop us a line, especially if you decide to adopt a green or other ig!
