About the Purple Pincher Hermit Crab
The Purple Pincher Hermit Crab, scientifically known as Coenobita clypeatus, is one of the most popular terrestrial hermit crab species in the pet trade. Native to the Caribbean and parts of the western Atlantic coast, these intriguing creatures are beloved for their colorful appearance and unique behaviors. Often mistaken as purely aquatic creatures, they actually spend a majority of their time on land, though they require a humid environment and access to freshwater.
Purple Pincher Hermit Crab Lifespan
In the wild, Purple Pincher Hermit Crabs can live up to 30 years, a testament to their adaptability and hardiness. However, in captivity, their lifespan is slightly reduced, typically ranging from 6 to 20 years. This discrepancy is often due to differences in diet, environment, and potential stressors that might be present in captivity.
Appearance
This particular hermit crab is easy to identify. Its name is derived from the deep purple coloration found on its large pinching claw. The rest of their exoskeleton can range in color from a reddish-brown to orange or tan. Their eyes are typically on long stalks, giving them a wide field of view.
Average Size
As they grow and mature, Purple Pincher Hermit Crabs can reach sizes of up to 4 inches when measured across their extended legs.

Tank Size
For a single Purple Pincher Hermit Crab, a 10-gallon tank is the recommended minimum. However, if you’re looking to house multiple hermit crabs, you’ll need to provide a larger environment to ensure each crab has enough space.
How To Set Up Their Tank
A terrestrial setup is essential. At least one-third of the tank should be sand or a sand-coconut fiber mixture, allowing the crab to burrow. Providing them with plenty of hiding spots using driftwood, rocks, or commercial hides is also essential. Ensure the tank has a tight-fitting lid to retain humidity.
Water Parameters (Water Type, Temperature, Hardness)
While Purple Pincher Hermit Crabs spend most of their time on land, they do require access to freshwater for drinking and saltwater for bathing. Neither should contain chlorine. The humidity level should be maintained between 70-80%.
Water PH
For the freshwater provided, a pH between 6.5 to 7.5 is ideal.
Temperature
Maintaining a temperature range of 70-85°F (21-29°C) ensures that the hermit crabs remain active and healthy.
Lighting
While Purple Pincher Hermit Crabs do not have specific lighting requirements, a regular day-night cycle is beneficial for them. This can be achieved using natural light or with a regular aquarium light on a timer.
Best Substrate for Purple Pincher Hermit Crab
A mixture of play sand and coconut fiber (coir) provides an ideal substrate. It holds moisture well, allowing for the necessary high humidity, and is also great for burrowing.
Reproduction of Purple Pincher Hermit Crab
Breeding Purple Pincher Hermit Crabs in captivity is a challenging endeavor. After mating, females lay their eggs and carry them until they’re ready to be released into saltwater. The larvae require specific conditions to develop and have a high mortality rate in captivity.
Disease Potential
Like all pets, Purple Pincher Hermit Crabs can fall victim to various diseases and health issues. Common ailments include mites, bacterial and fungal infections, and molting problems. Regular monitoring and maintaining a clean habitat can help in disease prevention.
Food & Diet
Being omnivores, Purple Pincher Hermit Crabs have a diverse diet. In the wild, they consume decaying wood, fallen fruit, and leaf litter. In captivity, a balanced diet of commercial hermit crab food, supplemented with fresh fruits, vegetables, and occasional protein sources like fish flakes, is recommended.
Behavior and Temperament
Known for their relatively docile nature, these hermit crabs are nocturnal, being more active during the evening. They often engage in activities like climbing, exploring, and burrowing.
Purple Pincher Hermit Crab and Suitable Tank Mates
While they can be kept with other hermit crabs of similar size, care should be taken to provide enough shells and space to prevent competition and aggression. They are generally not aggressive towards other tank inhabitants but can be territorial with their own kind.
Breeding
As previously mentioned, breeding these hermit crabs in captivity is challenging. Specific saltwater conditions are needed for the larvae to thrive. While some enthusiasts have had success, it requires detailed attention to water parameters, diet, and lighting conditions.
