That's an awesome guide! I definitely book marked it. How are WTFs abusive to a tank? I only have one right now and he's been pretty gentle on the tank so far so maybe I just haven't noticed? Oh my word, just as I was typing this I think I got an idea of what you meant. I looked up just in time to see him lunge from one end of a the tank to the other to snag a cricket off the pothos and in the process dislodged part of his climbing vine, nearly broke a leaf off the pothos and then splashed water everywhere when he landed in his water dish. And I didn't even know there was a cricket in there! So I guess I'll construct the vivarium keeping that sort of thing in mind :P.
