Can a moon crab live with a hermit crab?

Moon crabs and hermit crabs have different habitat requirements and behaviors, making them generally incompatible as tank mates. Moon crabs thrive in brackish environments and require a more terrestrial setup, while hermit crabs prefer saltwater and a sandy substrate. Additionally, moon crabs can be more aggressive, which could lead to stress or harm for the more docile hermit crabs. Therefore, it is best to keep them in separate environments to ensure their well-being.
