One recommendation I have found useful for new acquisitions to help them settle in is to cover three sides of the tank. I have thick poster paper that I cut to shape and stuck to the back and sides with double sided tape. This helps them to feel less exposed. I would definitely still pick up more ground clutter and a matching hide so that he has more than one to choose from. Really the more shelter and hiding spaces right now the better. Just look at the photo you posted of the initial set up and imagine how exposed you would feel in it, then do whatever you can think of to eliminate that exposure. Having just one side of the tank that they feel like a threat could come from seems to help them relax a ton. Do of course be careful to only cover the sides in a way that does not pose a fire hazard if you are using a heat lamp.![]()
