A bad smell from a hermit crab is usually a strong indicator that it has passed away, rather than just molting. When molting, hermit crabs will typically bury themselves in the substrate and remain still, but they shouldn't emit a foul odor. A dead hermit crab will decompose quickly, producing a distinctly unpleasant smell. While it's always worth ensuring they are truly deceased before disposal, a strong odor generally confirms this. Ensure you regularly check your crab's environment and provide appropriate care to support their health.
