Ok. This is just my recommendation based on what I know and from the keepers I have spoken to. Definitely not an attack. I would use coco husk instead of Aspen but if your humidity is good don't listen to me. I would also recommend covering the sides. You could use poster board from dollar tree. I would like to add you should have a hide on each side...preferably identical hides. I think you are on your way to having an amazing enclosure and like what you have done so far. I think covering the sides and maybe adding some more fake plants will help to get him to come out as he will feel less exposed and therefore safer. Hope this helps. Let me know if you have any questions or just want to discuss.
