I've been doing some looking around on the internet, trying to decide what to do. Here's my dilemma:

I have a very nice 30 gallon long aquarium just sitting empty in my apartment. The long top is covered by a wire mesh screen. I was wanting to sit this aquarium up on it's side and get an arboreal display animal of some sort. I was thinking about putting Pinky in there, but it's an awful big space for one little gecko. I was also thinking about getting a cham, but I don't know if they could deal with only one side being wire.

So I'm looking for recommendations. Snakes, lizards... something arboreal that could live in a 30 gallon space. Thanks in advance!
