Full Answer

  1. Observe the crab carefully

    Watch for small twitches on the part of the crab. Any movement at all indicates that the crab is still alive.

  2. Do not disturb a molting crab

    Protect a molting crab from other aquarium creatures. Don't disturb the crab yourself, as doing so during the molting process can be dangerous for the crab. Instead, surround the crab with a protective barrier so other aquarium creatures cannot reach it.

  3. Check for a rotting smell

    Sweep the sand at the bottom of the aquarium if a crab has buried itself, and check to see if the crab smells fishy. A dead crab starts to smell bad after a few days, while a molting crab has no unusual smell.
