Why do my crabs have little meetings where they group up for a bit, then scatter? Should I be worried? Do I need to sleep with one eye open? I think it is pretty weird.
Maybe dead fish has something that gets hermit crabs smashed o-oI think my hermits have an old empty shell they hide a mini-kegger in, and they all gather around it a couple times a week for a party, or to celebrate when something dies that they can all eat.
