HCA: Hermit Crab Association

So my Crabbies have been going nuts the last three days

The substrate is torn up, holes everywhere, and the cuttlebone is looking really rough. I have it stuck in the sub like a surf board.

So my question is, how often do you typically pull the surface decorations like hides out and smooth the substrate?

Don't want to undo good progress!

Ha!! Must be contagious, since mine have been crazy recently too. I generally smooth the substrate a couple times a week, or whenever it starts making my eye twitch. I don't usually pull out decorations and stuff since I'm lazy; I just smooth around them.

Only three holes are out in the open, but it's starting to look like there are sink holes under every hidey hut/decoration.

Ditto with my guys! What's up with our crabbies ? Like megmaholm, I tend to just smooth around the decor and lightly backfill any deep holes with the EE they've tossed out while "rampaging."

Maybe they can communicate with Santa and are planning their own party?

Mine are digging a lot also! Woke up this morning and, I swear, the whole tank looks like a mole went from one end to the other!

I fix it when I feed them. Usually when I sneak down to spy on them they have already tore it up. That usually ends with me grumbling and sometimes swearing when I go back upstairs.

I think it's some sort of seasonal thing for them, maybe preparation for breeding season? The first week of December everyone but two went down to molt at the same time, and now they've all came back up and there's hole under and next to everything, all three hides, two under the driftwood, one between the water dishes, and a giant uncountable minefield of craters under the moss pit. I'm going to wait until I stop seeing any new pits to clean and fix everything back up, don't wanna clean it up for nothing, it might encourage then to dig more!
