Can hermit crabs live under sand?
Sand is the substrate of choice for hermit crabs because they like to burrow down into it. Playground sand, which can be found at home improvement stores, works well and is inexpensive, though aquarium sand is fine as well. The fiber is ground quite fine and is nearly like soil, so it is good for burrowing.

How long do hermit crabs stay under the sand?
