What Do Hermit Crabs Eat?
What do hermit crabs eat in the wild, as pets, in the ocean, on land? The answer is the same… they are scavengers and will eat almost anything! However, hermit crabs do have nutritional needs so it’s important for them to eat a wide range of foods including proteins, vitamins and minerals and nutrients that are found in meats, veggies, fruits and other foods that we’ll list and expand on, below.
For this article, we’ll be focused on land hermit crabs and what they should be eating as pets. And some ideas for snacks !
Foods Hermit Crabs Like to Eat
The list of what hermit crabs can, and will eat, is long. Realistically, your hermit crab pets will eat most anything you feed to them.
However, to keep them healthy and living a long healthy life, it’s important to stick to foods and food groups that provide the nutrition they need.
| Food Group | Examples |
|---|---|
| Store-bought | Dried fruits, seeds, flowers are good (hard brown pellets = bad) |
| Proteins | Shrimp, crab, chicken, beef, pork, insects |
| Vegetables | Seaweed, carrot, corn, microgreens, kale, sweet potato |
| Fruits | Banana, apple, pineapple, avocado |
| Snacks | Popcorn, shredded coconut, millet seed, peanut butter |
Common Store-Bought Foods
Store-bought hermit crab foods are convenient options, but some of these foods are a bad choice. Most hermit crabs don’t recognize those store-bought hard little brown pellets as food, and they’ll most likely starve if this is all you feed to them. However, there are also some very good commercial hermit crab foods they come with their pros and cons:
Pros to feeding your hermit crab pets store-bought foods:
– Convenient and easy to store.
– Specifically formulated for hermit crabs.
– Good as a dry longer-lasting vacation food.
Cons:
– Most contain additives and preservatives.
– Can be expensive in the long run.
– Lack fresh micronutrients, vitamins and minerals
