I have a spare terrarium that measures 18 inches high, 12 inches wide and long, that I would like to use to house some kind of exotic animal to display. Preferably, I would like something that I can build a naturalistic set-up with, including live-plants and a cork background. Can I house a Green Tree Frog happily? If not, what other options do I have? I realise that I don't have much variety to choose from, but I do want to put something interesting in there. However, I don't want something that is going to be difficult to maintain, i.e. Dart Frogs.
