This is a totally ignorant curiosity based question, I’m new to this and I didn’t know!! I read glass tanks aren’t great for them because of lots of reasons like the heat and that they’ll hurt themselves if they can see out. Would putting a dark paper/wallpaper around the outside of 3/4 sides (front being open so you can see in) work? I only ask because I saw this on a Facebook group I joined *not my photo* and I thought maybe I could achieve it by using paper or something? Like I said I’m not sure. I know the guy I’m getting this week (Small adult Russian tortoise) comes with a 40 gallon glass tank and I didn’t know if there was a way I could turn it into an actual good home?
