I like it simple!

I use barrels and trash cans a lot, they keep the good stuff inn.
However I cut a window and glue a plexi for the lizard to have a view, I think they are curious about there surroundings.

In my 45 gal drums a single 25w bulb is enough, when females are gravid I lower the bulb near the ground until they nest, then I bring it back up again, it doesn’t get simpler then this.

I hope you will enjoy these lizards as much as your tree monitors, I find them much more fun and interesting.

Did you find a female boehmei yet?
