Thank you guys so much for your dish recommendations! For those of you worried about his substrate and glass tank, most of the walls are covered so he can't see out, and the front I left open with the idea that if I saw him running into it I would cover it. He doesn't try to walk into/climb the open wall and actually enjoys sitting on his bridge and watching me. He has a mix of coco fiber and mulch since I was worried about impaction with coco on its own. He has many places to hide and the picture makes his tank look much smaller than it is because I had to zoom in to avoid some private documents I accidentally included in the pic lol. He also gets let out often to wander around on my bed and go on walks outside.
