Strawberry Hermit Crab Species Profile and Identification

The Strawberry Hermit Crab (Coenobita perlatus) is uniquely identifiable by its vibrant red to strawberry pink color, hence the name. Native to the Indo-Pacific region, it thrives in coastal areas from the islands of Aldabra, Mauritius, and Seychelles through Samoa.

They have a distinct physicality, growing up to 3.15 inches (80mm) in length and weighing approximately 2.82 ounces (80g). The crabs’ bodies are well-equipped for survival. They’re decapods, meaning they have two sets of five appendages – some for locomotion, others for tasks such as feeding and defending.

Their special feature is their ability to occupy empty gastropod shells, which offers protection for their soft, coiled abdomen. These discarded shells give each crab its unique look! The crabs also have four antennae that help them sense their surroundings. Beware, though, they can look a little different based on the location, a phenomenon yet to be fully understood.

Sexual identification is interesting in these crabs. You can differentiate males from females only when they have exited their shells, based on their differentiated genital pores and the presence of a long coxal tube in males.

With the right care, these vibrant creatures can live up to 25-30 years in the wild but usually live for 1-4 years in captivity. As a bonus, these “nocturnal socialites” often travel in groups and live in colonies, making them an interesting addition to your home aquarium.

Strawberry Hermit Crab Supplies

You’ll need a variety of essential supplies to ensure your strawberry hermit crab (Coenobita perlatus) is happy and healthy. It’s crucial to plan and gather these supplies before bringing your new pet home.

  • Aquarium Tank: You’ll want an aquarium of at least 10 to 20 gallons (38 to 76 liters). These crabs are social creatures, so the space needs to accommodate a small group.
  • Substrate: This is the material that lines the bottom of the tank to simulate the crab’s natural environment. Use a mixture of sand and coconut fiber.
  • Hiding Spots: Create safe and stress-free places for your crab. This can be coconut hides, PVC pipes or aquarium decorations.
  • Heating Pad: Get a reptile-safe heating pad. It should be placed on one side of the tank to allow for a heat gradient.
  • Hygrometer and Thermometer: To monitor and maintain the correct humidity and temperature levels.
  • Water Dishes: One for fresh water and another for saltwater. Both should be shallow and easy to access.
  • Food Dish: A shallow dish for their food.
  • Climbing toys: Pieces of driftwood or cork bark are great options.
  • Extra Shells: Always keep extra unoccupied shells in the tank. Your crab might decide to move houses.

Caring for a strawberry hermit crab is a commitment. But, great rewards come with the right equipment and care. Your little friend will be thriving in no time.

Strawberry Hermit Crab Tank Setup

Setting up a conducive environment for your Strawberry Hermit Crab, Coenobita perlatus, is a crucial step to ensure a happy and healthy pet.

First off, you’ll need a spacious tank for your delightful little friend – a minimum of 10 gallons (37.8 litres) is recommended. The size of the tank relies heavily on the number of crabs you have. Make it a rule of thumb to add 2.5 gallons (9.5 litres) per crab.

Use a deep tank substrate. Opt for a mix of sand and coconut fibre. Ensure that it is deep enough – aim for about twice the size of your largest crab. This depth provides an avenue for your crabs to dig and molt, a natural process for them.

Remember, add climbing and hiding spaces. Hermit crabs enjoy scrambling around. Get them driftwood, fake plants or crab-friendly toys.

Proper temperature and humidity are vital. Reach 72-80°F (22-27°C) for temperature and 70-80% humidity level. Use a reliable thermometer and hygrometer to monitor these.

Lighting is not a must, but a small light can help replicate day-night cycles. But never expose the tank to direct sunlight, it can overheating your tank.

Lastly, keep a lid on your tank. It helps in maintaining humidity levels and also prevents adventurous crabs from escaping.

By following these setup rules, you can provide a comfortable and accommodating home for your strawberry hermit crabs.

Strawberry Hermit Crab Water Requirements

One of the vital aspects of strawberry hermit crab care is their water requirements. It’s significant to provide them with access to both freshwater and saltwater.

Freshwater is essential for them to drink, while saltwater is needed for their shell conditioning and moisture maintenance.

Crabs, in general, cannot tolerate chlorinated water thus you should always dechlorinate the water before providing it to your pet. You can do this using a water conditioner available at pet stores or let the water sit out in an open container for 24 hours to allow the chlorine to evaporate.

Furthermore, ensure you’re providing them with saline water that mimics their oceanic habitat. You can easily achieve this by adding aquarium salt, as per the package instructions, to dechlorinated water.

Here is a simple rundown of important points about their water requirements:

  • Provide both freshwater and saltwater.
  • Use dechlorinated water.
  • Add aquarium salt to the saltwater container.

Also, remember to check the water containers daily and refill them as needed. The water dishes should also be clean and shallow enough so the crabs can easily climb in and out.

One last bit of advice, always have a sponge or climbing accessory in the water dishes so the crabs don’t drown. Monitoring the humidity in their enclosure is crucial too, it must be around 70-80% which you can achieve by regularly misting the tank with water.

Strawberry Hermit Crab Diet and Feeding

Feeding your Strawberry Hermit Crab (Coenobita perlatus) entails understanding its role as a scavenger. The dietary habits of C. perlatus, also known as “garbage collectors of the seashore”, give them a unique preference for consuming a variety of dead and rotting material typically found along shorelines.

Here’s a table of their feeding preferences:

Preferred Food Type Examples
Carrion Dead and decaying animal matter
Detritus Decaying plants, leftovers, and waste

Although these crabs are not aggressive food fighters, it’s important to note they do require regular meals. Never keep them for long periods without access to food.

With their innate ability to store water in their shells, they have adapted to survive away from the sea, but it’s crucial to maintain a well-hydrated environment for them.

Integrate the following into their diet:

  • Carrion: Include meat-based protein like fish, shrimp or chicken leftovers (unseasoned).
  • Plant matter: Fruits, veggies, and leafy greens offer good nutrition. Ensure they’re all washed and cut into crab-friendly sizes.
  • Ocean goodies: Consider adding seaweed, cuttlebone, or crushed oyster shells for added minerals.

Remember, your C. perlatus will appreciate the change and variety in their meals. Additionally, cleanliness is key—after feeding, promptly remove any uneaten food to prevent spoilage and bacteria growth in your crab’s home. This diligent diet and feeding care caters to your hermit crab’s health, always encouraging its active and vibrant life.

Strawberry Hermit Crab Care Schedule

Your work as a strawberry hermit crab guardian operates on a routine. Consistency is key in maintaining a healthy environment for your crab.

  • Daily: Aim to mist your strawberry hermit crab’s habitat with dechlorinated, salt-free water daily. This keeps the humidity levels optimal and aids the crab’s breathing. Also, check the temperature and humidity levels to ensure they’re stable.
  • Weekly: A cleaning of the crab habitat should be done once a week. Remember to remove uneaten food and any waste. Be sure to provide fresh food and water daily, but a thorough checking of food and water dishes for cleanliness should be conducted weekly.
  • Monthly: More thorough tank cleaning should be done on a monthly basis. This involves spot cleaning, checking the substrate, and looking for any signs of mould or fungi.

Observation is crucial. Regularly watch your hermit crab’s behavior and keep an eye out for signs of stress or illness. If anything appears out of the ordinary, promptly consult with a vet.

In their molt stage, allow them solitude. This crucial growth phase could last from a few weeks to several months. Create a safe, disturbance-free space for your crab during this time.

Strawberry Hermit Crab Health Problems

When taking care of a Strawberry Hermit Crab, being aware of potential health problems is critical. Issues can arise from various sources such as poor habitat conditions, diet deficiency, and stress.

  • Molting Problems: Molting is a natural process for hermit crabs where they shed their exoskeleton to grow. If your crab is having trouble during this stage, it may be a sign of inadequate humidity or nutrition.
  • Shell Rot: Caused by unsuitable housing or unclean environments, shell rot can occur. It’s characterized by a foul smell and discolored or flaking shell; early detection and immediate clean up are vital.
  • Limb Loss: Stress, attacks from other pets, or accidents can result in limb loss. Provide a calm environment and isolate the injured crab to prevent further harm.
  • Dehydration: An essential part of a crab’s care is regular access to fresh and salt water. Dehydration is lethal to Strawberry Hermit Crabs.

Remember, the best way to keep your pet healthy is through preventative care, maintain a clean habitat, good diet, and proper handling. Should you notice any unusual behavior or symptoms, don’t wait, seek help from a vet familiar with exotic pets immediately.

Strawberry Hermit Crab Tank Mates

The choice of tank mates for your Strawberry Hermit Crab can significantly influence the well-being of your pet. You should be especially careful with this, as some tank mates can be harmful.

One important thing to remember is that Strawberry Hermit Crabs are highly social creatures. They thrive in groups, so the best tank mates are other Strawberry Hermit Crabs. Together, they can form small colonies, which can be fascinating to observe.

That being said, mixing species within the same tank should be done with caution. Other species of hermit crabs can coexist with Strawberry Hermit Crabs, but always make sure to research the specific needs and behavior of each species before introducing them.

Not all species of hermit crabs have the same salinity requirements or dietary preferences, so proper research can prevent potential conflicts or health issues.

As a general rule, avoid adding predatory fish or other creatures that could harm your Strawberry Hermit Crab. These include larger crabs, lobsters, and puffer fish, which are known to bother or even prey on hermit crabs.

  • The best tank mates are other Strawberry Hermit Crabs.
  • Other hermit crab species can be compatible, but research first.
  • Avoid predatory creatures that might harm your pet.

Remember, a stress-free environment with compatible companions is key to your Strawberry Hermit Crab’s happiness and longevity.

Strawberry Hermit Crab Breeding

Breeding Strawberry Hermit crabs at home could be a challenging task as they tend not to reproduce in captivity. However, if you’re seeking to facilitate this natural process, understanding their breeding behavior in the wild could guide you.

In the wild, male C. perlatus place a spermatophore, which is sperm packaged in a protective casing, on the female. This casing is then dissolved by secretions as the female releases around 10,000 to 50,000 eggs. Once fertilized, she carries them on her abdomen, moistening them with water stored in her shell.

After some time, the female then takes these eggs to the sea. She leaves them on wet sand or a rock, from where tide carries them out to sea. The eggs hatch there and the tiny larvae undergo planktonic development.

Young crabs are very small and molt several times while still at sea. After they reach adult size, they move to land. It’s now that they are vulnerable to predators until they find a shell to inhabit.

It’s important to note, even attempting to recreate these conditions at home does not guarantee your hermit crabs will breed. Their complex life cycle and specific breeding patterns often make successful breeding in home aquariums rare. The stress caused by forced breeding can also severely affect their health.


Venturing into the world of Strawberry Hermit Crab caretaking can be a rich and rewarding experience. If you’re attentive and committed, you will undoubtedly foster a beneficial environment for your new pet.
