Do Hermit Crabs like eating grapes

When you pick the food for your pet Hermit Crabs, you want it to fulfill two functions: to appeal to their taste as well as to add to their health. So, let us begin by talking about first things first: do Hermit Crabs like eating grapes?

First of all, grapes are sweet fruits, and all sweet fruits appeal to the taste buds of Hermit Crabs. Therefore, your pet Hermit Crabs will most likely eat these fruits. However, much like us, Hermit Crabs have their own individual taste. It is entirely possible that while some Hermit Crabs will love it, others might not touch them at all.

The best way to find out your pet’s preferences is to serve them grapes at least a couple of times. If the serving dish returns untouched both times, they are probably not fond of grapes. In that case, you should move on to another fruit; you have plenty of options to pick from.


Do grapes have health benefits for your pet Hermit Crabs?

By now, you must have figured out whether or not your pet Hermit Crabs like eating grapes. If they do, it is time for you to learn about the health benefits grapes have for their health.

If you go through the table carefully, you will notice that grapes are rich in a number of vitamins and minerals. However, how many of these nutrients are beneficial for your pet crabs?

Hermit Crabs are still one of the under-studied species, which is why we don’t have enough data to pinpoint their exact nutritional needs yet. But there are some nutrients that have been known to add to their health. Let us take a look at the nutrients in grapes that can meet these needs:



Carbohydrates are an essential nutrient for all living beings. They are the building blocks of energy for Hermit Crabs. Moreover, carbohydrates make up a small portion of chitin, a fibrous substance that is a major constituent of their exoskeleton. Grapes contain carbohydrates in abundance.



In order to process the vitamins from the food they consume, Hermit Crabs need fat molecules in their diet. Fats also help in building their cell membranes and are, therefore, indispensable. About 100 grams of grapes contain 0.18 grams of fat, which is enough to meet the dietary need of your pet crabs.



Amino acids make up protein, which maintains the health of the Hermit Crab’s soft tissue and exoskeleton. From grapes, they can acquire enough protein to suffice for their good health.



Much like shrimps and snails, Hermit Crabs need calcium for the maintenance of their exoskeleton and cell function as well. There is 10 mg of calcium present in 100 grams of grapes, which is plenty for your little pet friends.



There is no living creature alive who doesn’t antioxidants in their body to survive. Grapes contain two of these phytochemicals in abundance: proanthocyanidin and anthocyanin, both of which help the immunity systems of the Hermit Crabs.



Beta-carotene is a plant pigment present in all the richly-colored fruits and vegetables, including grapes. This plant pigment provides the Hermit Crabs with their rich color. A deficiency of beta-carotene in Hermit Crabs can make them appear duller or paler.

These six, among other nutrients, are the reason why grapes can be considered perfectly healthy for your little pet crabs.


Can baby Hermit Crabs eat grapes?

Yes, by all means. The diet of baby Hermit Crabs is not much different from their parents. Just like the adults, their younger ones are sturdy creatures who can eat almost anything. Grapes even have an advantage for them; these fruits are soft and squishy and are loved all the more for it.
