Fourth Instar
I just assembled everything for my latest addition, pictures of them in situ to come. I have a potting mixture and cocofiber substrate with magnolia leaves and sphagnum moss on top. This container might work well for a small roach colony as well. The two halves form a solid barrier and if you have climbers a small amount of screen could be added to the lid to prevent escape. It's called the Wonder Bubble.
