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.”
