What they do is simple. They eat, drink, sleep, and play! (They go to the bathroom, too, of course!) They climb all over wood and fun play toys found in a local pet store. They love to dig, too, and can bury themselves. I recommend not disturbing the animal while underground, for they may be molting. That's when they shed their outer layer of "skin," known as the exoskeleton, which is actually the outer skeleton of the crab. Without toys, hermit crabs like to hide, or sleep. Providing a dark, hiding spot is important. They like to hide away in small areas to rest. Some hermit crabs spend all day picking at water droplets on the side of the aquarium tank, which you should have. The tank and hermit crabs must be misted with water at least once a day. Without 80% humidity, the crabs may dry out and die.
some can but most live in very humid enviornments
You can buy hermit crabs at stores such as Petco. They have many hermit crabs things to meet your needs.
No, Hermit Crabs and Fiddler crabs require two different environments. The Hermit Crab would drown in the water a Fiddler Crab needs. You can always ask your local pet store if there is any way possible though. Some hermit crabs live on land others live in water even land hermit need two enter salt water , fiddler crabs are brackish or fresh hermit crabs can't breathe in those environments
