Housing and Habitat
When it comes to housing and habitat for hermit crabs, there are a few important things to keep in mind. Here are some sub-sections to help you get started:
Choosing the Right Tank
Hermit crabs need a tank that is big enough for them to move around in and explore. We recommend a glass tank that is at least 10 US gallons (38 liters) for every 2 crabs. Make sure the tank has a lid to keep your crabs from escaping and to help maintain the right humidity levels.
Substrate and Soil
The bottom of your tank should be covered with a substrate that is at least 2-3 inches deep. We recommend using a mix of silica play sand, soil, and/or coconut fiber. This will give your crabs a place to burrow and molt. Make sure the substrate is kept moist but not too wet.
Creating a Crabitat
To create a comfortable and stimulating environment for your hermit crabs, you can add some accessories to their tank. We recommend adding some larger empty seashells for your crabs to use as future housing, as well as some hiding places like rocks, logs, and plants. You can also add a shallow dish of fresh water and a dish of salt water for your crabs to drink and bathe in.
Enclosure Size and Lid
The size of your enclosure will depend on how many hermit crabs you have. As a general rule, you should have at least 5 gallons of space per crab. Make sure the enclosure has a lid to help maintain the right humidity levels and to keep your crabs from escaping. You can use a fish tank or reptile terrarium as an enclosure, just make sure it is the right size and has a secure lid.
Overall, it is important to create a comfortable and stimulating environment for your hermit crabs. By choosing the right tank, substrate, and accessories, you can help your crabs thrive in their new home.
Temperature and Humidity
Maintaining the proper temperature and humidity is crucial for the health and well-being of your hermit crab. In this section, we will discuss how to maintain the ideal temperature and humidity levels, as well as the use of a hygrometer and heater.

In conclusion, maintaining the proper temperature and humidity is essential for the health and well-being of your hermit crab. By using a hygrometer and heater, you can ensure that your hermit crab is living in a comfortable and healthy environment.
Feeding and Nutrition
Hermit Crab Diet
As responsible pet owners, we must provide our hermit crabs with a balanced diet that mimics what they would eat in the wild. In their natural habitat, hermit crabs are omnivores and feed on a variety of foods such as fruits, vegetables, and even dead animals. In captivity, it is recommended to provide them with a commercial hermit crab food that contains a mix of pellets, dried fruits, and vegetables.
It is important to note that hermit crabs are selective eaters and may not eat all the food provided. Therefore, it is recommended to offer a variety of foods to ensure they are getting all the necessary nutrients. Fresh fruits and vegetables can also be provided as a supplement to their commercial food.
Feeding Schedule
Hermit crabs are nocturnal creatures and are most active at night. Therefore, it is best to feed them at night when they are most active. It is recommended to offer food every other day and remove any uneaten food after 24 hours to prevent mold growth and bacterial infections.
Nutritional Requirements
Hermit crabs require a balanced diet that is high in protein, calcium, and other essential vitamins and minerals. Commercial hermit crab food should contain at least 20% protein and 2% calcium. It is also important to provide them with a freshwater dish and a saltwater dish to maintain their hydration and electrolyte balance.
In addition to their food, hermit crabs also require a source of calcium to maintain their exoskeleton. Crushed eggshells or cuttlebone can be provided as a source of calcium.
Overall, providing a balanced diet and following a regular feeding schedule is crucial for the health and well-being of our hermit crabs.
Water and Hydration
Fresh and Saltwater Requirements
As hermit crabs are land creatures, they require access to both freshwater and saltwater to stay hydrated. It is essential to provide your hermit crab with two shallow dishes, one for freshwater and the other for marine-grade saltwater. Both dishes should be just deep enough so that the hermit crab can submerge itself completely. It’s important to note that hermit crabs cannot breathe underwater, so make sure the dishes are not too deep.
Dechlorinating Tap Water
Tap water contains chlorine, which is harmful to hermit crabs. Therefore, it is crucial to dechlorinate tap water before offering it to your hermit crab. You can use a dechlorinator that is safe for aquatic animals and plants, or let the water sit for 24 hours before using it. During this time, the chlorine will evaporate, and the water will be safe for your hermit crab.
Water Dishes and Bowls
It’s important to keep the sides of the dishes low enough so that the crab can get out easily. Also, make sure to clean and refill the dishes daily to prevent bacterial growth and ensure that your hermit crab has access to clean water at all times. You can use a reptile water conditioner to keep the water clean and healthy for your hermit crab.
In summary, providing your hermit crab with access to freshwater and marine-grade saltwater is essential for their hydration and overall health. Make sure to dechlorinate tap water and keep the water dishes clean and refilled daily to ensure that your hermit crab has access to clean and safe water.
Hermit Crab Shells
As hermit crabs grow, they need to change shells to accommodate their increasing size. Shells are not just a simple accessory for a hermit crab, they are a vital part of their habitat. In this section, we will discuss the importance of shells and how to choose the right ones for your hermit crab.
Importance of Shells
A hermit crab’s shell is more than just a home. It protects their soft abdomen and regulates moisture within the shell, which is important for the function of the gills for breathing. Without the right shell, a hermit crab can become stressed, sick, or even die.
Choosing the Right Shell
Choosing the right shell is crucial for your hermit crab’s health and happiness. Here are some things to keep in mind when selecting shells:
- Size: A shell should be big enough for your hermit crab to comfortably fit inside, but not so big that it feels exposed and vulnerable. A good rule of thumb is to provide at least three similarly-sized shells per hermit crab, with at least two being slightly larger.
- Type: Hermit crabs prefer seashells with a round opening, such as those of snails or whelks. Avoid shells with sharp edges or narrow openings, as they can harm your hermit crab or prevent them from entering or exiting the shell.
- Condition: Choose shells that are in good condition, without cracks or holes. Cracks and holes can let in air and dry out the shell, making it uninhabitable for your hermit crab.
- Variety: Give your hermit crab a selection of shells to choose from. They may have a preference for a certain type of shell or a particular color.
In conclusion, shells are an essential part of a hermit crab’s habitat. Choosing the right shells can make a big difference in your hermit crab’s health and happiness. By providing a variety of shells in different sizes and types, you can ensure that your hermit crab has a safe and comfortable home.
