16. Please describe the emergency situation in detail.
One of the crabs (the most active one) changed shells and immediately went underground afterwards and has been underground for 2ish weeks,maybe more. She was above ground for a solid 2 weeks and very active beforehand.
I assume she is molting. I was wetting the substrate near the UTH as it was starting to dry out. As I was lightly fluffing only the top layer, I found a tunnel. It didn't collapse completely but I did kick a little dirt in the entrance. It's still maintained it's shape but some semi moist, semi dry sand fell in. Didn't completely seal it off. I can still see the entrance. Should I be worried? It was completely sealed off with the top layer of completely dry sand so I wasn't able to see it beforehand
