If you’re setting up a paludarium and considering hermit crabs as residents, you’re not alone. These fascinating creatures can thrive in the right environment, but it’s crucial to understand their needs. In this article, we’ll explore the ins and outs of keeping hermit crabs in a paludarium, which types of crabs are best suited for these setups, and how to create an ideal environment for them.

Can Hermit Crabs Live in a Paludarium?

Yes, hermit crabs can definitely live in a paludarium! These aquatic and terrestrial hybrids require an environment that mimics their natural habitat. Paludariums, which combine both land and water features, offer the perfect setting. To successfully house hermit crabs in a paludarium, ensure the following:

  1. Tank Size: Minimum 10 Gallons Hermit crabs need a decent amount of space. A minimum of 10 gallons per hermit crab is essential to ensure they have room to roam. If your paludarium is larger, you can divide it into sections, but you’ll need to adjust the water levels for the crabs to thrive.
  2. Live Rock for Stability and Shelter Live rocks are vital in a paludarium. Not only do they provide a stable habitat, but they also offer hiding spots and surfaces for the hermit crabs to climb. Choose rocks with small protrusions to give the crabs plenty of places to explore and hide.
  3. Maintain a Consistent Temperature Hermit crabs thrive in warm conditions. The water and land areas of your paludarium should stay within a temperature range of 75-80°F. If you’re in a cooler climate, use a heater to maintain a steady temperature. This will help replicate the tropical environment hermit crabs naturally inhabit.
  4. Provide Plenty of Hiding Spots Hermit crabs need to feel safe, so your paludarium should have plenty of hiding spots. Live plants, rocks, and other structures can give them the privacy they need. If your paludarium is sparse, consider adding shells or small houses where the crabs can retreat to when they feel threatened.
  5. Use the Right Substrate The substrate in a paludarium should mimic the natural environment of the hermit crabs. The substrate needs to be nutrient-rich and capable of proper drainage. A depth of at least 1-2 inches (2-5 cm) is required for the crabs to burrow and stay comfortable. Organic options like EcoEarth work well and are easy to maintain.
  6. Humidity is Key Hermit crabs require high humidity levels to stay healthy, so it’s essential to keep the humidity in the 70-80% range. This can be achieved by using a humidifier or misting the enclosure. Ensure that the crabs have access to both fresh and saltwater to stay hydrated.
  7. Water – Fresh and Saltwater Hermit crabs need access to both fresh and saltwater. A mixture of the two provides the best environment. Be sure to provide shallow bowls for both types of water. The fresh water helps hydrate the crabs, while the saltwater is necessary for molting and other biological functions.
  8. Regular Cleaning Maintaining a clean environment is crucial. Vacuum the gravel regularly and use a siphon to clear out debris. This will prevent harmful bacteria buildup and ensure a healthier environment for your hermit crabs.
  9. Add a Waterfall for Movement Not only do waterfalls add an aesthetic appeal to the paludarium, but they also create beneficial water currents. Hermit crabs can enjoy swimming and exercising in these currents. Set up the waterfall in a location where it won’t disturb the crabs’ favorite resting places, and ensure it’s creating gentle water movement.

Can Hermit Crabs Live in a Terrarium?

While hermit crabs can live in a terrarium, it’s not the ideal setup. A terrarium typically lacks the aquatic features needed to create a balanced habitat for hermit crabs. For hermit crabs to thrive, they need access to both land and water, which is why a paludarium is a better choice.

For terrariums, the tank should be at least 5 gallons per hermit crab, with open sides for air circulation. While terrariums can maintain the humidity and temperature levels necessary for hermit crabs, they must not be closed off completely. In a sealed terrarium, the air exchange is limited, which can cause humidity and temperature imbalances that can stress your hermit crabs.

Can You Keep a Hermit Crab in an Aquarium?

Yes, hermit crabs can live in aquariums, but there are some key considerations. The tank should have a glass cover to maintain humidity and temperature control. A temperature range of 68-86°F is ideal.

You will also need to provide both saltwater and fresh water, and consider adding live food to their diet. Be careful not to let the water temperature exceed 90°F, as this can overheat the crabs. The best crabs for an aquarium setup are marine hermit crabs, which do well in saltwater environments and tolerate higher temperatures. Always ensure that the tank is well-maintained and that the crabs have access to plenty of food and hiding spots.

Can Hermit Crabs Live Submerged in Water?

Hermit crabs are both land and aquatic creatures, but they cannot live fully submerged in water for long periods. They need a mix of land and water to thrive. Marine hermit crabs can live in saltwater for extended periods, but they must come to land to breathe, mate, and lay eggs. If you’re planning on keeping hermit crabs submerged in water, make sure the tank has an air pump or bubbler to allow the crabs to breathe. Marine hermit crabs are better suited for this environment than land hermit crabs.

What Hermit Crabs Are Best for a Paludarium?

Some hermit crab species are more suited to paludarium life than others. Here are the best options:

  1. Australian Land Hermit Crab Ideal for paludariums due to its tolerance for stable temperature environments, the Australian Land Hermit Crab is a great addition to any paludarium setup.
  2. Purple Pincher Hermit Crab This colorful, active crab thrives in paludariums. It appreciates the more consistent temperature and humidity levels provided by a paludarium.
  3. Snowy Hermit Crab Known for its ability to survive in cooler climates, the Snowy Hermit Crab is another species that can adapt to paludarium conditions. However, it is less active than the Purple Pincher.
  4. Blueberry Hermit Crab Although blueberry hermit crabs can live in a paludarium, they aren’t the best fit. They require a different temperature range and may not thrive in the tropical conditions ideal for other species.
  5. Ecuadorian Hermit Crab Ecuadorian hermit crabs are better suited to environments with more fluctuating temperatures, so they’re not the best choice for a paludarium.

How Big of a Tank Do You Need for a Hermit Crab?

To keep hermit crabs in a paludarium, you’ll need at least 10 gallons of tank space for one crab. If you plan to keep multiple crabs, you should provide 5 gallons of space for each one. A spacious tank gives your hermit crabs enough room to explore and thrive while ensuring that they have the necessary resources, such as water, food, and space to burrow.

Final Thoughts

Hermit crabs are fascinating creatures that can thrive in a paludarium if provided with the right environment. Maintaining the correct temperature, humidity, and water conditions is essential for their well-being. For the best results, opt for species like the Australian Land Hermit Crab and Purple Pincher Hermit Crab, which are well-suited to life in a paludarium.

With proper care and setup, hermit crabs can live happily in a paludarium, providing an engaging and low-maintenance pet experience.
