She's been very busy the past week. The tunnel is so long now that it wraps the perimeter of the tank all the way to the left front, opposite from where the log starting point is. I knew terrestrial Ts burrowed but, wow.
Whenever she's not digging I often see her poised at the entrance. So many legs I can't even see her face.
Want to add more dirt since the substrate has settled to the point where half the tank is empty space but I'm worried I might collapse her tunnels in the process. I've heard that Ts reinforce their burrows with webbing to prevent this though so maybe if I'm careful it shouldn't be an issue?
