Hermit Crab Care Guide: Creating a Happy Home for Your Tiny Crustacean Companion

Hermit Crab Care Guide

1. Selecting the Right Hermit Crab Species

Before diving into hermit crab care, it’s crucial to choose the right species for your environment. The most commonly kept pet hermit crab species are the Purple Pincher (Coenobita clypeatus) and the Ecuadorian hermit crab (Coenobita compressus). Make sure to research and select a species that will thrive in your specific climate and available resources.

2. Providing Suitable Housing

Hermit crabs require an enclosure that mimics their natural habitat as closely as possible. A glass or plastic terrarium with a secure lid is an excellent choice. The enclosure should have proper ventilation to maintain humidity levels and prevent mold growth. Here’s what you’ll need:


  • A mix of sand and coconut coir or peat moss to create a moist, sandy substrate.


  • Hermit crabs use empty snail shells as their homes, so provide a variety of sizes and shapes for them to choose from.

Heat and Humidity:

  • Maintain a temperature range of 75-85°F (24-29°C) and humidity levels of 70-80%. Use a heat pad or lamp to achieve the right temperature.

3. Feeding Your Hermit Crabs

Hermit crabs are omnivorous scavengers, and their diet should be diverse. Offer them a balanced diet consisting of:

  • Commercial hermit crab food: Look for high-quality, pelleted hermit crab food at pet stores.
  • Fresh fruits and vegetables: Include items like apples, bananas, carrots, and leafy greens.
  • Protein sources: Provide options such as cooked chicken, fish, and small amounts of scrambled eggs.
  • Calcium: Offer crushed eggshells or cuttlebone for their exoskeleton health.

Ensure a shallow dish of fresh, dechlorinated water and a separate dish with saltwater (marine aquarium salt mix) for their hydration and molting needs.

4. Maintaining a Clean Environment

Cleanliness is vital for hermit crab health. Regularly clean their food and water dishes, as well as any waste they produce. Also, spot-clean the substrate to remove any uneaten food, molted exoskeletons, or waste.

5. Social Interaction and Enrichment

Hermit crabs are social creatures and thrive when kept in groups. A solitary hermit crab may become stressed and unhappy. Aim for at least two to three hermit crabs in your enclosure to provide them with companionship.

Additionally, enrich their environment with items like climbing structures, shells, and hiding places. They enjoy exploring their habitat and will benefit from a stimulating environment.

6. Molting and Shell Changes

Hermit crabs molt to grow, shedding their exoskeletons. During this time, they may bury themselves in the substrate for weeks or even months. Do not disturb them during molting, as it’s a delicate and vulnerable process.

After molting, your hermit crab may seek out a new shell, as they outgrow their old one. Ensure a variety of empty shells are available to accommodate their changing needs.

7. Health and Medical Care

Regularly monitor your hermit crabs for signs of illness, stress, or abnormal behavior. Common health issues include shell rot, mites, and bacterial infections. If you suspect any health problems, consult a veterinarian experienced in hermit crab care.

8. Lifespan and Growth

Hermit crabs can live for several years if well cared for. Their growth and lifespan depend on factors like diet, environment, and overall care. Be prepared for a long-term commitment when adopting these intriguing creatures.
