I sit for 15-20 min each night before bed and watch them. They come out of their hides like clock work unless its the week before a shed. At 8pm they start climbing like monkeys hahaha. So graceful that it chills me out watching them before bed.
Ohhh and I bet you could always sell your smaller enclosure if you wanted to upgrade.... The 18" high is the smallest I'd go just for the simple fact mine love to climb.
