    No, most crabs will only be 1-3 inches in size.

    Yes, but they can grow and it is always better to replicate their habitat by getting a crab tank. The bigger place, the better.

    Community Answer
    Sand crabs are generally sustained by salt water when they live in the ocean, but they can adapt to fresh water when living in a home tank environment.

    Can my hermit crab live in freshwater?
    Community Answer
    No, an aquatic hermit crab will need salt water. A land hermit crab will need both fresh and salt water pools, and a land section in their enclosure.
