Land Crabs as Pets: Complete Care Guide & Fascinating Facts

Land crabs are fascinating invertebrates that can make excellent pets for enthusiasts seeking something different from traditional pets. These crustaceans mainly inhabit the edges of watery environments rather than living fully aquatic lives, making them uniquely suited to terrarium-style habitats. Keeping land crabs offers an engaging, educational experience with relatively low daily maintenance.

Two popular species commonly kept as pets in the UK are the Rainbow Land Crab and the Halloween Land Crab. Both species are hardy, remain manageable in size, and require a habitat that provides both land and water areas. Their vivid colours and fascinating behaviours make them visually stunning and captivating pets, perfect for curious pet owners.

Choosing the Right Land Crab Species for Your Home

The Rainbow Land Crab dazzles with hues of purple, blue, orange, and cream, brightening any terrarium. The Halloween Land Crab, by contrast, features a striking black body with orange legs and purple markings on its claws, offering a dramatic look. Despite their land preference, these crabs need access to fresh water and benefit from environments that closely mimic their natural habitats.

Setting Up Suitable Housing for Land Crabs

Land crabs thrive in enclosures that combine both terrestrial and aquatic features. A tank about two feet long and equally wide and deep is sufficient for a pair, creating enough territory to prevent overcrowding and conflict. The substrate should involve an appropriate sand that supports burrowing and retains shape when moist, as crabs often create burrows on the land side of the tank.

Building a sloping beach area that meets a water zone about three to four inches deep encourages natural behaviours. Aquarium furniture or driftwood can be used to stabilise the sand banks from erosion. Though small and shallow, the water area should be fitted with a gentle filtration system to maintain cleanliness and prevent stagnation.

It is crucial never to keep fish with land crabs in the water part of the tank, as crabs are known to prey on aquarium fish.

Maintaining Temperature and Environment

Maintaining adequate moisture is critical; humid conditions should keep the sand moist naturally due to proximity to water. If the sand dries out, it may indicate insufficient water area or environmental dryness. Both Rainbow and Halloween Land Crabs hail from warmer climates, so a heat mat set to around 22C placed beneath the water area helps maintain ambient temperature. This warmth transfers through the substrate to the land section, ensuring overall habitat comfort.

Water used should be treated and dechlorinated similarly to fish tank water to prevent harm to the crabs. Importantly, these crabs live in freshwater environments and do not require saltwater that hermit crabs sometimes need.

Providing a Balanced Diet for Land Crabs

Land crabs are omnivorous scavengers and require a varied diet reminiscent of their natural intake. Commercial hermit crab foods are suitable, as are traditional fish foods, raw fish, and a range of vegetables like potatoes and apples. A calcium source, such as a cuttlefish bone placed within the enclosure, is essential to maintain healthy shell growth.

Feeding your land crabs a well-rounded diet helps support their health and vitality, making regular meal provision both simple and rewarding.

Where to Find and Buy Land Crabs

While some larger pet shops may stock land crabs, your best option for reputable pets is specialist exotic pet or aquarium retailers. Private breeders or sellers with expertise in land crab care can also be a reliable source. For convenience, land crabs can occasionally be found listed for sale in the invertebrates section on Pets4Homes.

Unique and Fun Facts About Land Crabs

• Land crabs can live for up to 10 to 20 years in captivity, with some species reaching over 30 years in the wild.
• They communicate using chirps and display complex social behaviours, making them fascinating to observe.
• Despite their tough appearance, they are not aggressive and tolerate handling well when socialised properly.
• Their vibrant colours make them visually striking additions to any exotic pet collection.

Responsible Care and Ownership

Before committing to land crab ownership, consider that they require a dedicated tank with specific environmental conditions and regular care, including tank maintenance and monitoring during moulting periods. Acquiring from reputable breeders or specialists ensures you receive healthy specimens bred and cared for ethically.

With appropriate investment in habitat setup and diet, land crabs can offer a rewarding introduction to keeping exotic invertebrate pets, showcasing nature's diversity in your home.
