Tunnel collapses

[Jamison]

Two of my crabs are underground and are probably going to molt. My substrate is not quite sandcastle consistency. Is this a problem.

I’m not sure except to say potentially- but I’m glad you asked bc I noticed my 10 gal is a bit on the dry side as well, and I have no idea where one of mine is other than buried. Another tunneled through last night and it seems to be holding ok for now. I’m concerned Pat went down for a molt, and now I’ve added 2 more friends to his tank that he’s never even met, and I worry they’ll meet under the substrate! So yes, any additional info on how best for each of us to proceed is appreciated!!

Is it just the top inch or so that’s dry? You should be able to just spray it with water.

It’s possible that crabs may encounter each other underground, but their tunneling usually means there’re no issues as long as there’s enough substrate.

Ok I uust found one of them on the surface. My substrate is not very dry just not quite sandcastle.

As long as you can form a tunnel by sticking your finger in it, you should be ok.

Sweet. Yes, it’s just that top bit that is a little more exposed. Thanks- that totally answers the question for me at least, and I feel a bit better now. Since there is a visible tunnel that goes at least couple inches down and back, I’d guess I’m ok, but a little spritzing is in order!

You can add a bit of water at a time along the side of the tank where the sand meets the glass. The water will dissipate into the substrate and not cause flooding as long as you don't add too much. I have seen where some admins add more than I do, but I tend to be a bit conservative. I will add maybe a half-cup, divided into a number of spots in the tank (I have a 55 gallon).

Can this be done every day?

Probably not. It could cause flooding. It shouldn't have to be done every day. Or often. Are all your crabs buried? If not you can remove them for a bit and fix the substrate to sandcastle consistancy. Mix it with dechlorinated water. If you squeeze it and it drips that's too wet.

Also note that it’s normal for the top inch or so of sand to become a little dry. In most cases it won’t affect the crabs’ ability to dig.
