Hermit Crabs need vitamins and minerals to stay healthy just as we do. Although the studies about their specific nutritional needs are still in process, scientists have come up with some nutrients that are essential for their health.

Let us take a look at what these are.



Of all the nutrients the Hermit Crabs need, calcium is by far the most important. It is essential for maintaining the health of their exoskeleton. A deficiency of calcium in their body can lead to the withering away of their shells. Apples contain calcium in a moderate quantity to support their shell health.



Although Hermit Crabs are heavily dependent on meat and meat products for protein, plant proteins are vital for them as well. The protein present in apples is enough to meet their nutritional needs.



Hermit Crabs are fond of all the richly-colored fruits and vegetables due to the presence of carotene in them. Carotene is an important micronutrient in their diet, and a deficiency of it shows in the color of their body after molting. Apple is rich in beta-carotene.



Antioxidants play a key role in maintaining the cell health of all living beings, including Hermit Crabs. Fortunately, apples contain these nutrients in abundance.


Therefore, it is safe to assume that apples are one of the healthiest fruits for your Hermit Crabs.
