This is TANK, he is a Water Salvatore Monitor. He is almost 2 years old. He will grow over 6'. He is a great eater. Very inquisitive. He roams my lizard room freely. Gets along great with other large lizards, such as iguanas, tegus, and my mangrove monitor. The associate at the per store where I bought him bares scares from him due to being startled. He has fairly aggressive when I got him, but he just needed to know I wasn't gonna stand for it. You have to show dominance with these young males.. they are like teenage boys!
