I haven't built a custom cage for him yet, he is still in a glass tank for the time being as I am focusing on finishing my tegu and Blueys' cages. That being said he will probably end up in a 4x2x2 cage down the road. On the last few pics of that thread you will see my current cage as it sits today with plenty of rocks, wood pieces, branches, dirt substrate and moss. I cover the top of the cage with a towel over the screen for now and provide a LED light for the day/night cycle. I also covered the 3 sides of his enclosure so that he couldn't see out of it. You need to give your lil guy some time, they are so tiny, I'd say once you get the enclosure setup right let him settle for a month and you will see him out exploring. IMO those hides are way too big. Mine has never used a hide like that. I put pieces of cork flat in the cage and he wedged himself in there when he wants to hide. (I am not saying my setup is perfect, and there are many ways to care for each snake) but I have seen positive changes in his behavior and activity when providing him with the setup I have now. Any questions feel free to ask.
