After a lot of trial and error, my boyfriend and I (mostly him, I have to admit) have finished Lewis' terrarium. It is the Zoomed 12x12x18, and has rocks carved out of pink foam, covered in grout and painted, with a waterfall and a couple of water drips. There is a false bottom with the pump under it. For substrate, we used the Atlanta Botanical Garden mix, and right now the plants are all on the smaller side, but I'm hoping the creeping fig will take off on the wall and provide a little more cover up top.

Lewis is loving having space to roam and hunt versus his 2 gal. fish bowl, so it's working out well. He was a little confused by the waterfall at first though and tried to eat it.
