So, I have 3 millipedes in a good sized terrarium. (I got the millipedes 2 days ago). I have 2 Desert Millipedes and 1 Texas Millipede. There is 5 inches of substrate, as well as some lichen sticks and a water bowl. The Desert Millipedes are adapting well, burrowing and climbing, but the Texas Millipede is not. It uncurls sometimes, but not often. My friend has a Texan as well, but his is adapting fine. Help please!
