It's likely... also if you hold it up and gently wiggle it, and it's loose or it falls out of the shell, maybe, but try leaving it in the cage more cause it might be molting(shedding).
If there is a STRONG fishy odor coming from the crab it means that he is dead.
The odor is a dead give-away. If it is smelling particularly fishy or of ammonia, it is going-going-gone.
Not necessarily. Hermit crab do spend some time sitting to destress or simply take a nap. If a hermit crab is completely unresponsive it may be a number of problems but first check your humidity and temperature as they can be early culprits of inactivity.
You can tell if crab legs are bad by checking for a strong fishy odor, slimy texture, or discoloration. If they have any of these signs, it's best not to eat them to avoid getting sick.
A rotting dead hermit crab typically exhibits a discolored, often darkened shell, with visible signs of decay such as mold or a foul odor. The meat inside may appear slimy, and the eyes or antennae can show signs of deterioration or detachment. The shell may also be empty or partially filled with decomposing matter, attracting insects or other scavengers. Overall, the crab's once vibrant colors are replaced by dull, murky tones.
The bacteria responsible for causing a fishy odor is called trimethylamine-producing bacteria.
No, ascorbic acid, also known as vitamin C, does not lead to a fishy body odor. A fishy body odor may be caused by other factors such as diet, certain medications, or medical conditions.
Pick up the crab, if it droops out of its shell kind of it probably molted and that is its exoskeleton and it is just a hollow discard. Look behind it and the actual crab will be there. Wait a couple days, keep giving it food and water but if you eventually start to smell a strong fishy odor the crab has died. Its probably just a molt.

The smell of the fish should be salty, not sort of a rotten smell.The fishy smell is a dead giveaway that it is no longer fresh.
trimethylamine
The chicken smells fishy because it may have been stored or cooked near fish or seafood, causing it to absorb the fishy odor.
