HCA: Hermit Crab Association

Hello,
Today I was taking my crabs/some decor out of their tank to do a little rearranging. One of my crabs was holding onto a barnacle bundle, and when lifting the barnacle (and crab) out of the tank, she let go and landed on her shell onto the wooden floor, probably 2-3 feet down.
She seems okay. I notice moisture around/on her and near the shell entrance, which I assume is from the water in her shell being shaken around.
No lost limbs, no shell damage. What should I do? Do you think she'll be okay?

Thank you!

All you can really do is watch and wait to see what happens. Chances are she will be fine, but there really isn't anything special or extra you can do.

There's always the chance for a fluke injury from falling, but I can tell you this has happened to multiple crabs of mine over the years in similar circumstances and they were always fine.
