What Do Hermit Crabs Eat? Hermit crabs are omnivorous scavengers, feeding on a variety of plant material, small animals, and decaying organic matter.
This varied diet is essential for keeping pet hermit crabs healthy and maintaining their natural foraging instincts.
The Diet of Hermit Crabs in the Wild
In the wild, hermit crabs are opportunistic feeders, meaning they consume whatever food sources are available in their environment. Their diet is diverse, providing them with all the necessary nutrients they need to thrive.
Plant Material and Fruits
Hermit crabs are known to feed on a variety of plant-based foods. In their natural habitats, they forage for fruits, leaves, and other vegetation.
- Fruits: Wild hermit crabs enjoy fruits like coconut, mango, and papaya. These provide vitamins and hydration, particularly in tropical regions where these crabs live.
- Vegetables and seaweed: They also feed on plants like seagrass and seaweed, which are rich in essential minerals and nutrients.
Small Animals and Invertebrates
Although hermit crabs primarily feed on plant material, they also consume small invertebrates and animal matter when available.
- Insects: Hermit crabs will eat insects such as flies and beetles, which offer a good source of protein.
- Carrion: These crabs are scavengers, and they often consume dead animals they come across. This provides them with essential fats and proteins.

Feeding Pet Hermit Crabs
To keep pet hermit crabs healthy, it’s essential to provide a varied diet that includes fresh fruits, vegetables, and protein sources.
While commercial hermit crab food can be part of their diet, it shouldn’t be the only food offered.
Fruits like apples, grapes, and bananas, along with leafy greens such as spinach, kale, and seaweed, are great for vitamins and hydration.
For protein, small portions of cooked meats like chicken or fish, or pet-safe insects like mealworms, help maintain their exoskeletons and overall health.
According to Dr. Michael Braun, a marine biologist, “Protein is crucial for hermit crabs, especially during molting when they need extra nutrients to strengthen their new exoskeletons.”
Foods to Avoid When Feeding Hermit Crabs
While hermit crabs can eat a wide variety of foods, certain items can be harmful to their health. It’s important to avoid feeding them any processed human foods or toxic substances.
- Junk food: Foods like chips, candy, and processed meats are harmful to hermit crabs and should be avoided entirely.
- Seasoned meats: Avoid giving hermit crabs meats that have been seasoned with salt, spices, or oils.
- Onions and garlic: These are highly toxic to hermit crabs and should never be part of their diet.
- Citrus fruits: Lemons, oranges, and other citrus fruits can irritate their digestive systems, so it’s best to avoid offering these.
Feeding Schedule and Tips
Since hermit crabs are nocturnal, it’s best to feed them in the evening, removing uneaten food the next morning to avoid spoilage.
They should be fed daily with a balanced mix of fruits, vegetables, and proteins in small portions, adjusted based on what they consume.
Fresh, chlorine-free water and access to saltwater for bathing and hydration are also important.
Additionally, calcium is essential for their exoskeletons, especially during molting.
You can provide calcium through supplements like crushed eggshells, cuttlebone, or by dusting their food with calcium powder.
Hermit Crab Paradise emphasizes that a varied diet, including calcium-rich foods, is key to keeping hermit crabs healthy.
Conclusion
Hermit crabs are omnivorous scavengers that eat a wide variety of plant and animal matter, including fruits, vegetables, small insects, and carrion.
When kept as pets, it’s important to provide a balanced diet that includes both fresh foods and proteins to keep them healthy.
Ensuring a proper diet will not only promote their well-being but also help them thrive in captivity.
FAQs
Hermit crabs should be fed daily with a variety of fruits, vegetables, and proteins, while any uneaten food should be removed the next morning to avoid spoilage.
Although they can eat small amounts of bread, it’s not recommended due to its low nutritional value.
Instead, focus on nutritious fresh foods. Additionally, hermit crabs require both fresh and saltwater, with saltwater essential for bathing and maintaining their internal water balance.
