Hermit Crab Without Shell?

Hermit crabs are nice little pets that can live for up to 20 30 years with you if you take care of them properly. Despite their small size, and the fact they probably look easy enough to look after, they require a great deal of maintenance, and something can easily go wrong. For example, they might suddenly start leaving their shells and refusing to return into it.

When crabs feel like they are in danger, they retreat into their shells immediately, as they do not really have other ways of protecting themselves. Because it borrows snail shells to live in, it simply might be that Hermit crab has found something better and more comfortable to wear.

There might be sand, mites, fungus (a bacterial or fungal infection might be causing your crab a skin disease), or other foreign objects lodged inside of it. To prevent this, there should always be an ample selection of shells of various sizes and styles in the habitat, so every crab can find something that suits them. The ideal humidity ( moisture ) for these crabs is about 80 percent, and the warmth should be of various sizes in different ends of the habitat, ranging from 87 85F (25 30C).

Before they reach the pet stores, the conditions in which they are harvested and transported are quite inhumane and make them suffer. The best way to start is to rinse or boil the abandoned shell and shake it thoroughly, as mentioned before, so that anything that might not belong in there gets removed. Pour out most of the water from the shell and place it in a cup or a bowl, depending on the size of the crab.

Add some dechlorinated sea salt water into the bowl to prevent the crab from drying out and dehydrating. Take the crab carefully from its enclosure by lightly holding it just behind the last pair of walking legs, or use a spoon to gently scoop it up. If the crab takes longer to move into a shell, provide it with easy access to food and water too.

You can use the cut bottle method, but be aware that, while it will prevent threats from above, it will not stop the crab from burrowing in the ground, so if it goes deeper, it can exit the protective dome.

If you have noticed that it likes a particular shape or style of the house, place several of the similar shells around it, preferably a bit larger than the one it has been living in before.

What Is Shell Evacuation?

Shell evacuation happens when your crab needs to “trade up” both its housing and its exoskeleton in order to accommodate its larger body size. It will leave its current shell in order to find a more suitable one. That said, not all who abandon ship are molting. Stress, an inhospitable environment, poor fitting shell (too large, too small, too heavy) and uninvited company can all cause a hermit crab to exit its shell. When this happens, your homeless crab suddenly becomes exposed to his surroundings, becoming too dry, and leaving it lethargic. Sometimes, sitting back and watching is all you can do.

Symptoms of Shell Evacuation in Hermit Crabs

You may also notice your crab acting lethargic. Maybe its legs and body have taken on a light beige hue. Its eyes may appear to face outward and its antennae may have ceased activity. If you notice any of these symptoms and your crab‘s environment is impeccable, wait it out. Your crab may soon shed its exoskeleton (molt). After it molts it will want to move into a bigger shell, so be sure you always have multiple sizes of empty shells in the habitat with hermit crabs.

Treatment

Sometimes evacuation is caused by factors other than molting, like a problem with your crab‘s environment. Humidity levels in its habitat could be too low or too high (ideal humidity ranges from 70 to 80 percent) or the temperature could be too hot.

Is the side of the food dish to high, or is another crab playing bully and preventing it from eating?In a tank with more than one crab, housing scuffles can ensue. Crabs may fight over desirable shells and they have also been known to steal another’s shell while the homeless crab was “trying out” an empty one.
