Ok, I finally narrowed it down to what species of plated lizard I own. Now before you get on my case, determining species based on pictures from the internet is tough as heck. They're all basically the same. Finally I found out I have a Gerrhosaurus Nigrolineatus. As opposed to the yellow throated I thought I had, which is more common.
I finally made my judgement based on the fact that it's throat is white. And yellow throated have red sides and red tails. Where as mine has red sides with no red tails. Real subtle.
So research has told me that my guy will get 18". He's 9 inches now, and big already, with a regenerated tail. Making it tough to judge his size. I'd bet he'd be 12-13 inches long. So he's got a way to go. Plus he's gonna get fatter.
I'm getting some collared green tonight, along with kiwi and oranges. I hope it goes well. I got a friend who owns a uromastyx, a veggie eating herp, he supplied me with a sweet list.
