How Much Does Hermit Crab Cost

Who knew that hermit crabs can become domesticated pets? Well, just in case you didn’t know, these shelled creatures are considered as well-known pets because of their peculiar behavior. One distinctive thing about them is their habit of transferring from one shell to another shell, as they grow bigger. Apparently, a lot of pet stores sell these crabs because many pet owners would actually buy them.

But contrary to popular beliefs, hermit crabs are difficult to take care, unlike cats and dogs. They need a high maintenance to keep them healthy and should never be away from their groups. It’s hard for them to live on their own. That’s why, if you wish to take care a hermit crab, you need to make sure that you are capable of providing everything it needs. Otherwise, it will just eventually die.

Additional Costs

If you think about it, the price of a hermit crab is not that expensive as compared to other kinds of pets. What makes it expensive is its shelter, as well as its everyday maintenance and supplies. Remember that you need to provide its natural habitat so that it can thrive and live longer than expected. On that note, let’s discuss the additional costs you have to take note in caring for a hermit crab.


Luckily, hermit crabs munch on anything, even peanuts and popcorn, so you don’t have to spend so much on their food. They are omnivores, which means they eat what humans basically consume such as fruits, vegetables, meats, and processed foods. But if you want ready-made food, you can purchase packs of hermit crab food made of pellets or a variety of their natural diet. They cost around $3 to $11, depending on the pack’s weight. There is also a specialized snack made of natural peanuts, which you can buy around $1.50 for 1.85 ounces, and flavored, powdered treats for $8 a pack. You also need the following:

– a food bowl that costs $1.50 to $9; or you can have a dish for both food and water for $5;

– a bottle of saltwater, which costs around $2 to $3; hermit crabs need salt water since they basically live in the sea; a saltwater conditioner costs $6 to $7;

– and a bottle of fresh water solution about $2 to $3 as well.


The most common equipment you can use as the hermit crab’s shelter and habitat is an aquarium. What works best for these sea creatures is a glass aquarium that can contain 10 gallons of water or more and comes with a secure lid. It will cost your around $30 to $50. You can also choose a plastic-made shelter that costs between $25 and $35.

Once you have purchased the shelter, transform it into the natural habitat of the crab. Basically, make it look like the beach by putting the following:

– sand                                    $5 to $15

– substrate                          $3 to $5

– bedding                             $3 to $6

– hideout                             $4 to $10

– climbing branch              $3 to $4

– toys or ornaments        $3 to $10


Apparently, hermit crabs need heat to live, that’s why you should have a heating source in their alternative environment. The most efficient source of heat is a light bulb, which costs $6 to $20. Apart from the heat source, you also need to monitor the temperature and humidity level (70 percent is the ideal level) in the crab’s habitat.

– a thermometer for the temperature                    $4

– a hygrometer for the humidity                                $5

– a combination of both apparatus                           $6 to $12


Sea  Hermit Crab

As previously mentioned, one of the unique characteristics of hermit crabs is their ability to move or transfer from one shell to another. For this reason, you need enough supplies of shells for your hermit crab. Put, at least, two artificial shells in the aquarium so that it can enjoy its move out adventures. The shells cost from $2 to $20 each, depending on the shell’s design and size. Colorful or highly-decorated shells are likely more expensive than simple shells.


If you don’t want to set up the habitat of your hermit crab, then you can buy a starter kit that comes with the necessary accessories. The kit usually comes with food, sand, shells, water and food dish, thermometer, saltwater conditioner, sea sponge, toys, ornaments, and even a care book. The cost of a hermit crab starter kit ranges from $12 to $33, but the price depends on the number of accessories it includes.
