I have one on my 29 gallon treefrog tank. I find him highly entertaining. He spends a lot of time basking on a log in the back, which gets up to 85 or so during the day. Occaisionally I see him on the screen, closer to the lights, where temp reaches a bit higher. He eats small crickets, calcium dusted, and drinks from water sprayed on the leaves (live plants). He's FAST, and hard to catch when I need to change the tank out. He's not at all handle-able, so if you are looking for a lizard to hold and handle, don't get a house gecko.
Any other specific questions, let me know.
