So my husband is researching these guys right now, but he doesn't have an account here so I'll be asking for him.

What are some of the details of daily life with a blue tongue you feel care sheets leave out or don't address? I ask that because for example we have found our rescue leopard gecko LOVES to climb; I had made a decorative wall for her cage and she's busy scaling it every day. When we're moved in August I'm going to get her a 20L and build something that will give her lots of places to explore and climb. Likewise I found out my Baird's Ratsnakes like to dig/tunnel in deep aspen more than they like to use their hides, so now I give them much thicker substrate for that.

So...do Northern Blue Tongues like to dig? Do they favor soil (Bioactive substrate) or aspen for that? Do they like climbing shallow gradients/gentle slopes? Do they like to hunt for treats in their cage? That kind of thing. I know that reptiles don't require enrichment in the same way that mammals do, but if it doesn't hurt them to provide it and lets a BTS exhibit some natural behaviors we'd like to give them enrichment options.
