How Do You Take Care of a Land Hermit Crab as a Pet?
Taking care of a land hermit crab involves creating a suitable humid environment, providing appropriate food and water, and offering opportunities for molting and socialization. By following these essential steps, you can ensure a long and healthy life for your land hermit crab as a beloved pet.
Introduction: A Guide to Happy Crabs
Land hermit crabs, with their charming sideways scuttles and borrowed shells, make surprisingly rewarding pets. However, responsible ownership requires understanding their specific needs. Originating from tropical coastal regions, these crustaceans thrive in warm, humid environments and require a diet tailored to their omnivorous nature. This article provides a comprehensive guide on how do you take care of a land hermit crab as a pet?, covering everything from setting up the perfect crabitat to understanding their unique molting process.
Creating the Perfect Crabitat
The crabitat, or the hermit crab’s enclosure, is crucial for their well-being. Mimicking their natural habitat is key.
- Tank Size: At a minimum, provide a 10-gallon tank for two small to medium-sized crabs. Larger crabs, or more crabs, require a larger space. A 20-gallon long tank is a good starting point for a few crabs. Remember, they need room to move around and bury themselves.
- Substrate: The substrate, or bottom layer of the tank, should consist of a mixture of play sand and coconut fiber (Eco Earth) that is at least 6 inches deep. This allows them to bury themselves for molting. The substrate must be kept moist but not soggy.
- Humidity and Temperature: Maintain a humidity level of 70-80% using a hygrometer. Temperature should be between 70-85°F (21-29°C). Use a heat mat on the side or back of the tank, not underneath, to provide warmth. Mist the tank daily with dechlorinated water.
- Water Dishes: Provide two shallow dishes of water: one with dechlorinated fresh water and one with dechlorinated salt water. Use marine salt, not table salt. The dishes should be easy for the crabs to access but deep enough for them to submerge themselves.
- Climbing and Hiding: Offer plenty of climbing opportunities with branches, rocks (ensure they are secure), and other decorations. Provide multiple hiding places, such as coconut shells or artificial caves.
Feeding Your Land Hermit Crab
Hermit crabs are omnivores and enjoy a varied diet. How do you take care of a land hermit crab as a pet? Part of it is providing them with enough food.
- Commercial Crab Food: High-quality commercial hermit crab food can form the base of their diet.
- Fruits and Vegetables: Offer a variety of fresh fruits and vegetables such as mangoes, apples, bananas, grapes, carrots, and spinach.
- Protein: Provide protein sources like unsalted nuts, dried shrimp, cooked eggs, and mealworms.
- Calcium: Calcium is essential for shell growth. Offer a cuttlebone or crushed oyster shells in their enclosure.
- Avoid: Avoid feeding them citrus fruits, onions, garlic, avocado, processed foods, and anything with preservatives or artificial colors.
Understanding the Molting Process
Molting is a critical part of a land hermit crab’s life cycle.
- Preparation: Before molting, crabs become less active, eat more, and may dig down into the substrate.
- The Molt: During the molt, the crab sheds its exoskeleton. This process can take several weeks.
- Post-Molt: After molting, the crab is soft and vulnerable. They will eat their shed exoskeleton to regain nutrients and harden their new shell.
- Do Not Disturb: Never disturb a crab that is molting. Isolate them if necessary to prevent other crabs from bothering them. Provide extra humidity and calcium.
Shell Selection: Providing the Right Home
Land hermit crabs require shells to protect their soft abdomens. Providing a variety of appropriately sized shells is crucial.
- Shell Types: Offer shells made of natural materials like turbo shells. Avoid painted shells, as the paint can be toxic.
- Shell Size: The opening of the new shell should be slightly larger than the one the crab is currently wearing.
- Shell Quantity: Provide several shells per crab, in varying sizes and shapes.
- Cleaning: Boil new shells in dechlorinated water before placing them in the tank.
Common Mistakes in Hermit Crab Care
Avoiding these common mistakes is crucial for ensuring the health and happiness of your land hermit crabs.
- Insufficient Humidity: Low humidity can lead to suffocation.
- Incorrect Substrate: Substrate that is too dry or too shallow will hinder molting.
- Lack of Shells: Not providing enough shells can cause stress and aggression.
- Improper Diet: Feeding the wrong foods can lead to nutritional deficiencies.
- Disturbing Molting Crabs: Disrupting the molting process can be fatal.
- Using Tap Water: Tap water contains chlorine and chloramine, which are harmful to hermit crabs.

Frequently Asked Questions (FAQs)
What size tank do I need for my hermit crabs?
As mentioned, a 10-gallon tank is the minimum size for two small to medium-sized land hermit crabs. However, larger is always better. A 20-gallon long tank is ideal for two to three crabs. You’ll need to increase the tank size as your crabs grow, or if you add more crabs to your colony.
How often do hermit crabs need to be fed?
You should provide fresh food and water daily. Remove any uneaten food after 24 hours to prevent mold and bacteria growth. Offer a variety of foods to ensure they receive a balanced diet.
How do I maintain the humidity in my hermit crab tank?
Maintain humidity by misting the tank with dechlorinated water daily, using a hygrometer to monitor the levels. A covered tank will help retain moisture. You can also use a bubbler in the water dish to increase humidity.
Why is my hermit crab not moving?
If your hermit crab is buried in the substrate, it is likely molting. Do not disturb it. If it’s above ground and not moving, it could be stressed, ill, or nearing a molt. Check the temperature and humidity levels, and ensure it has access to food and water.
How do I know if my hermit crab needs a new shell?
If your hermit crab is constantly trying to enter other crabs’ shells, or if it appears cramped in its current shell, it likely needs a larger shell. Provide a variety of shells in different sizes and shapes.
What do I do if my hermit crab gets mites?
Mites are common in hermit crab tanks. Improve the hygiene of the tank by cleaning it thoroughly. Replace the substrate and boil decorations. You can also use a reptile-safe mite spray, following the instructions carefully.
Can hermit crabs drown?
Yes, hermit crabs can drown if they get stuck in deep water. Always provide shallow water dishes with rocks or sponges for them to climb out on. Make sure they can easily exit the water source.
How long do hermit crabs live?
With proper care, land hermit crabs can live for 10-30 years in captivity. Factors such as diet, habitat, and stress levels can affect their lifespan.
Can I handle my hermit crab?
While you can handle your hermit crab, it’s best to limit handling as it can be stressful for them. Always wash your hands before and after handling, and be gentle. Avoid dropping them, as this can cause serious injury.
What kind of water do I use for my hermit crab?
Always use dechlorinated fresh and salt water. You can purchase dechlorinating drops from a pet store. Use marine salt for the saltwater dish, not table salt.
How do I clean my hermit crab tank?
Spot clean the tank daily, removing any uneaten food and feces. Perform a deep clean every few months, replacing the substrate and cleaning the decorations. Avoid using harsh chemicals or soaps.
How do you take care of a land hermit crab as a pet?
The key to answering how do you take care of a land hermit crab as a pet? is to understand that their environment, diet, and molting processes are essential to consider. By creating a suitable habitat, providing a varied diet, and understanding their molting needs, you can ensure a long and healthy life for your hermit crab.
