I cannot think of any disadvantages to the closed chamber, it’s perfect… but how can I visually enjoy him and his habitat I lovingly created. I know tortoises aren’t pick-up-and-handle-any-time pets, I treat him like the coolest most spoiled garden gnome ever. My conditions for him are perfect when humidity and temps and lights but now that he isn’t struggling with glass, it’s difficult to be able to monitor him clear as day like I used to and have closure visually he’s okay. Should I set aside my human wants of being able to see him and keep him in the Rubbermaid? I know it’s best for him but could a viewing port be added without stressing him?
