Quick question I love the Exo Terra vivariums I think they are so beautful and I was thinking about purchasing one for my jungle corn whose about 2 years old and about 2 1/2 feet long. The vivarium is 45x45x60cm. I have heard that corns get stressed out in large spaces, would this vivarium be too big for him? I thought maybe since he's older and loves to climb he would enjoy the new vivarium. Thanks
