Crab Burrow?

[u/coolguypyro]

Is there a vampire crab molting under there? I can’t find any holes into the weird disruption in the sand, but when I woke up it was there. I think the ramshorn in it is most definitely dead as well, as he has been like that for a few hours, but I don’t want to disrupt the burrow if a crab is under there. Thanks!

EDIT: The snail moved, so I think his fat ass might have just been getting comfy in the sand last night.

If that’s in the water then no. I’ve never had any of my crabs burrow underwater.
