I have three in a 12 x 12 x 16 tank, with a ponytail palm planted in it. I also suctioned a fake vine to the side of the tank, and I have a cork bark background, and a small water bowl. They seem to be very happy in their tank, and they love the palm. They occasionally swing from the leaves like Tarzan, and they enjoy sitting on the trunk. I spray the tank about once or twice a day, and keep it at room temperature. I use a lamp on top, but its just a regular light bulb to make sure the palm is getting enough light.
