Fruits and Vegetables for Hermit Crab FoodWhat types of food does a hermit crabs diet consist of? How much food should you feed your hermies? And how often should you feed them? Yes, all these questions need answering, but first, let's go over the most important thing in a hermit crabs diet...



Calcium is an essential part of a hermit crabs diet, and in order to ensure that your pet hermies live long, happy, healthy lives, it is extremely important that you provide your pets with a healthy dose of calcium carbonate (CaCO3). Here's why...


Adding calcium to a hermit crabs diet will aid in the growth and development of their exoskeletons. Like all arthropods and similar to reptiles, hermit crabs undergo a molting process where they shed their "skin", making way for a newly developed layer of skin/exoskeleton that requires calcium to grow efficiently and effectively.


Without a healthy dose of calcium in their diet, hermit crabs will not grow, develop and molt properly and as a result, they simply won't live as long.


To make sure that hermit crabs do grow, develop and molt properly, try sprinkling some calcium in the form of powder their food before you offer it.


What, how and when do you feed hermit crabs?

As you'll quickly see, hermit crabs are omnivores, meaning that they eat both plants and animals. Their diet is very diverse, ranging from lettuce to dog food! Here's a list of some things that you can feed your hermit crabs...

So, there's lots of nutritious things to feed your hermies, many of which you can find at your local pet or grocery store, or even in your cupboard or refrigerator at home. Just be sure you consider the following couple things before you offer your hermies their meal...

  1. Hermit crabs don't eat a whole lot of food, try not to over-feed them. A teaspoon full of food is great for several hermit crabs.
  2. Feeding your hermies once a day is good. Just make sure that you remove any uneaten food at the end of the day so that it doesn't go to waste, and doesn't create any unhealthy, unpleasant odors!

Hermit crab owners usually try to do their best to offer their pet hermies the right food containing a good dose of calcium and the right amount of nutrients. And while there are lots of things to feed your hermies at your local grocery store and in your home, you should definitely consider offering a few foods that already contain these essential ingredients. For example...


Calcium Supplements
Hermit crabs need a healthy dose of calcium to ensure growth and development of their exoskeletons.
