Hermit crabs are very interesting and unique pets, but did you know their housing setup is very important to their health and happiness. Hermit crabs are small repetitive creatures that cannot thrive without their surroundings and need the perfect house for hermit crab. If you’re new to hermit crabs or are simply looking for more information,
Unique Characteristics of Hermit Crabs
Hermit crabs are no ordinary pets. Quirky in behavior and shell-dependent for life, these crustaceans are some of the most interesting characters around. Let’s explore what makes those so special and outlined for housing, and why that housing is so critical.
Anatomy and Behavior
Hermit crabs have soft, vulnerable abdomens, which is why they reside in shells for protection. Unlike most animals that grow their own homes (snails, for example), hermit crabs have to find new, larger shells as they grow. Therefore, they are always finding ways and means to upgrade themselves — this is what makes them unique!
Why Do Hermit Crabs Require Homes?
Not only do hermit crabs rely on their shells and habitat for protection, they also rely on them for comfort. This is important because a proper house for hermit crab has their door(s) placed in a way that looks out as an indoor space, making them feel safe while still being able to replicate their natural burrowing, climbing, and exploring behaviors. The wrong housing and hermits can get stressed, unhealthy and die.

In the wild, hermit crabs reside in tropical conditions with ready access to wet sand, warm temperatures, and many hiding places. Creating these circumstances in captivity is crucial for their welfare. An unsuitable environment can cause dehydration, stress and ultimately death.
What Do Hermit Crabs Need in Their Housing
The key to making the perfect habitat for your hermit crabs is to make sure all their needs are covered. Let’s look closely at the essential ingredients of a happy and healthy crabitat.

Space Requirements
- Hermit crabs require ample space to move around, explore, and grow. Here is what you need to know about tank sizes:
- Minimum Space Per Crab: Experts recommend at least 1 gallon of space per holostean, higher if its a different kind.
Recommended Tank Sizes:
- For 1–2 small hermit crabs: 10-gallon tank is suitable.
- For larger groups or larger crabs: A 20-gallon tank or larger.
Why space matters: Hermit crabs are very active animals. They require space to roam, climb and dig. A tank that’s too small can be stressful and restrict feeding behaviors.
Substrate Depth
The substrate is the material that covers the ground of your hermit crab’s habitat. Its very presence is paramount to their comfort and burrowing ability.
Depth of Substrate: Ideally, there should be at least 2–3 inches of substrate for small crabs, while large crabs may require 4–6 inches or more.
Best Substrate Options:
Sand: Fine, moist sand is great for burrowing.
Coconut Fiber: The soft and absorbent texture of coconut fiber make it another great option.
The Reason Substrate Is Important: Hermit crabs dig into the substrate to regulate temperature, molt (shed their exoskeleton) and feel safe. Coarse substrates, like gravel or sharp substances can injure them.
Accessories in the Habitat
Hermit crabs are happiest in conditions that closely resemble their natural environment. Adding accessories helps make their home more wonderful and comfortable.
- Climbing Toys: Most hermit crabs enjoy climbing. Add driftwood, climbing nets or textured surfaces.
- Hiding Huts: These are small shelters or tunnels that your crabs can hide in and feel safe.
- Additional Shells: Always have a range of larger shells in the tank in case your crabs need an upgrade.
Selection of the Right Hermit Crab House
Choosing the appropriate materials and sizes for your hermit crab’s space is vital. In this post we will outline why a tank is perfect for hermit crabs.
Tank Material
- Glass Tanks ~ Holds heat and humidity keeping it great for hermit crab habitats.
- Plastic Tanks: Very light and inexpensive, but they do not hold temperature and humidity as well.
- Which Is Better? As they are generally easier to work with, glass tanks are widely used, particularly for keeping conditions stable.
Tank Dimensions
- The actual size of the cage determines how much usable space your hermit crabs have. For example:
- The typical 10-gallon tank size is roughly 20 x 10 x 12 inches, giving more than enough space for a few small crabs.
- Higher and larger tanks allow for taller climbing structures and bigger ventilation.
Lid and Security
- Hermit crabs are escape artists! Yes, they’ll need a tight lid to keep them safe.
- Tightly Fitting Lids – Keeps escapes at bay while holding heat and moisture.
- Sliding Screen Lids: Provides better ventilation with protection for your crabs.
The Importance of a Safe Space
After purchasing the correct tank, it’s time to set it up in a way that will check all the boxes for your hermit crab!
Maintain proper temperature and humidity
- Temperature: Maintain tank temperature at 70–85°F (20–29°C). If required use a heat mat or lamp.
- Humidity: Aim for approximately 70–80% humidity. Mist the tank with non-chlorinated water; or use a damp sponge.
- Why It Matters: Hermit crabs breathe using modified gills and need a humid environment in order to survive.
Lighting Conditions
- Do not place the tank in direct sunlight this will make it overheat.
- Select a quiet, low-traffic location so there’s as little stress as possible.
Hideaways and climbing structures
- This also adds to their security so provide hiding spots like coconut huts or tunnels.
- Include some wood pieces to provide climbing surfaces and promote natural behaviors.
Avoiding Mistakes in Hermit Crab Housing
Even with the best intentions, it’s hard not to mess up. Some common traps to watch out for are:
Inadequate Space
A tank that’s too small will stress out your hermit crab and inhibit his activity. A larger tank than you think you need always!
Poor Substrate Choices
The gravel or any sharp material may damage your hermit crabs. Stick with more innocuous choices such as sand or coconut fiber.
Overlooking Temperature and Humidity
Failure to maintain proper conditions may lead them to dehydrate and die.
How to gradually enhance your hermit crab house
- As your hermit crabs age, their requirements will evolve. Here’s how to update their habitat:
- Scaling Up Tank Size Transition to larger tanks as your crabs grow or if you add more crabs
- More accessories: New climbing toys, shells, and hideaways for stimulation.
For the creative, you can even build your own hermit crab habitat. Here’s how:
Building Your Own Crabitat
- Materials: Glass tanks, coconut shells, and driftwood
- Ensure the setup is secure and achieves optimal humidity.
Creative Hideaway Ideas
- Use natural material such as coconut shells or driftwood.
- Arrange the accessories to create a tropical environment.
Conclusion
Providing the right shelter for hermit crab is important for their health and happiness. From proper tank size to temperature and humidity control, no detail is too small. Take the time and effort to invest in a proper setup, and in return your hermit crab will reward you with their spirited interactions.
