Can Hermit Crabs Eat Vegetables: Benefits and Best Veggies for Hermit Crabs!

Yes, hermit crabs can eat certain vegetables. Hermit crabs are omnivores – meaning they enjoy various foods, including vegetables. However, it’s important to introduce vegetables slowly to your crab, so they don’t get sick. So if you decide to give your crab vegetables, be sure to wash them first and cut them up small for the crab to eat quickly. 

How Often Should Hermit Crabs Eat Vegetables?

Feeding them vegetables every other day is recommended as this is the average time they live on a shellfish diet. If fresh vegetables are kept in the water dish, your hermit crab will devour them. 

Benefits of Feeding Vegetables to Hermit Crabs

Feeding them vegetables provides them with essential vitamins and minerals and fresh, healthy foods that they wouldn’t find in their natural environment. Some of the best vegetable choices for feeding hermit crabs include peas, green beans, and cucumbers. Not only do they meet their nutritional needs, but feeding plants to hermit crabs introduces some much-needed enrichment into their lives. This can be a fun way to help them learn about and explore their surrounding environment.

Vegetables Recommended for Hermit Crabs


Asparagus is delicious as it is low in sugar and high in minerals, making it a perfect vegetable for hermit crabs. You can cook asparagus or give it to them raw – both work fine!

Beans and Legumes

Beans and legumes make great food for hermit crabs. These omnivorous creatures will consume various vegetables, including beans, legumes, peas, green bell peppers, cucumbers, and other fresh fruits and vegetables. For those that like crunchier textures in their food options (hermit crabs are known for being picky eaters!), choosing vegetables that are easy to digest is a good idea – like beans and legumes!


Beetroot is a great vegetable to feed hermit crabs as it is low in sugar and has plenty of nutrients. You can also give them other vegetables like sweetcorn, broccoli, carrots, etc., but be careful not to overfeed them as this will lead to obesity and health problems. Keep an eye on their water intake – if they drink a lot, you are doing fine!


Broccoli is high in calcium and other nutrients, so it will keep them healthy and happy. Feed them a small amount of broccoli daily to keep them fit and content. Hermit crabs love dark green vegetables like broccoli, so make sure you include some in their diet regularly.


Cabbage is an excellent food for hermit crabs as it provides them with plenty of variety and fresh vegetables. Some of the vegetables that hermit crabs can eat include kale, spinach, and cabbage. Make sure to feed them small amounts several times a day, so they don’t get too full or obese.


You can give them fresh or frozen cauliflower and feed them small amounts multiple times per day to ensure they get the appropriate amount of nutrients. Other vegetables you can give your hermit crab include broccoli, brussels sprouts, kale, and other cruciferous vegetables.


Carrots are great if you want an excellent vegetable to feed your hermit crabs. They are highly nutritious and easily digestible, making them an ideal food choice for these little scavengers.


Cucumbers are a high water content food, making them perfect for hermit crabs. In addition to feeding your hermit crab cucumber pieces, you can give them a whole cucumber or cut it into small pieces for them to eat. So if you have leftover fresh-cut cucumbers, don’t hesitate to share them with your pet reptiles.


Eggplant is a great vegetable to feed your hermit crabs as it offers lots of variety in terms of taste and nutrition. Depending on their preference, you can give them raw eggplant or cooked. Make sure to give them enough space, so they don’t get overwhelmed with too many new flavors.

Green Beans and Peas

Green beans and peas offer a high amount of Vitamin C. In addition, these veggies make an excellent treat or food supplement for the crab every day. You can also mix them with fresh vegetables to ensure the hermit crabs don’t get bored. 


Lettuces have high water content and soft texture making them very appealing to these crustaceans, while you can also feed other vegetables such as cucumbers, zucchini, and squash to them if they are fresh. Remember that lettuces should not be pesticide-treated or herbicide-grown – this could prove harmful to your crab!

Sea Vegetables

Sea vegetables provide hermit crabs with essential nutrients and many health benefits. Some of the most common sea vegetable hermit crabs will eat include cucumbers, zucchini, tomatoes, and leafy greens.


Tomatoes are sumptuous for hermit crabs as they are soft and easy to chew. You can feed them whole or cut the tomatoes into small pieces, making them ideal for small hermit crabs. Make sure to give them enough water, so they don’t get dehydrated.

Are Any Vegetables Unsafe for Hermit Crabs?

It’s always important to consult your hermit crab’s veterinarian before feeding them vegetables as a regular diet. While some vegetables are okay to give, others may contain harmful chemicals that could cause health problems. For example, while broccoli is generally safe for hermit crabs to eat, it may contain harmful oxalates that can cause calcium oxalate kidney stones. If you’re unsure whether or not your vegetable is safe for your crab, err on the side of caution and avoid feeding it to them altogether. 

Why Won’t My Hermit Crabs Eat Vegetables?


If you’ve tried moving your hermit crab to a new home and he still doesn’t seem interested in eating vegetables, it may be due to overfamiliarity. If he is used to being in one place, his diet may not include the same variety of food as what he is accustomed to. Another possible explanation could be that your hermit crab isn’t comfortable with the change. To test this theory, try feeding him small pieces of vegetables instead of entire vegetables at first. He might take some time getting used to the taste but eventually should start accepting them willingly.

Inappropriate Environment

There is a good chance that your pet hermit crab isn’t adjusting well to his new home. If he still doesn’t seem to be getting along well after feeding him small pieces of vegetables every other day for a week, it may be time to get him a different type of pet.

Negative Prior Experience

If your hermit crab has had a negative experience in the past with vegetables, it may not want to eat them again. Instead, you could try feeding them fresh vegetables daily or mixing them with their regular food to overcome this. If that still doesn’t work, you could try buying them vegetable-specific food pellets or other specially designed feeders. 

For example, hermit crabs are omnivores and have a natural diet that includes vegetables – so adopting a strategy like this should help get them to eat veggies again!
