HCA: Hermit Crab Association

Hi guys, have a look at my set up below, I am worried that the crabs will fall from the top and land on the hard water dishes below.

Is this a concern? Or will they be skilled enough to not fall?

Crabs fall all the time. In the wild they can drop several feet up from trees. You'll hear them clacking when they do. Shouldn't be an issue

Thank you guys
