I broke down and bought a two month old Argentine at a show today. It's the best animal I've ever kept as far as first days go. It chowed on 7 huge lobster roaches immediately! It's amazing how much less skittish this one is compared to my big Colombian. She's not a biter, but her claws tear up the hands during cleaning sessions. This little one just scopes things out, gives me a quick look, and then relaxes in my lap. I can't wait for him to get huge.
