What Do Hermit Crabs Eat?

Hermit crabs are omnivores, meaning they eat both plant and animal matter.

In the wild, hermit crabs mainly feed on live plants and animals, such as seaweed, algae, small crustaceans, and mollusks.

They also eat decaying material, such as fallen leaves, bark, and driftwood.

Hermit crabs in the wild also scavenge for food, meaning they go around looking for food that other animals have left behind.

This includes food scraps, dead animals, and other types of decomposing organic matter.

In addition to these foods, hermit crabs also enjoy eating fruits and vegetables.

Buy Hermit Crab Food

If you don’t have the time or inclination to make your own food, there are many commercially prepared hermit crab foods available on the market.

These generally contain a mix of proteins, carbohydrates, and vitamins, as well as added minerals for extra nutrition.

These foods often come in a variety of forms, including pellets, flakes, and freeze-dried treats.

Be sure to look for a high-quality product with no artificial colors or flavors, as these can be harmful to hermit crabs.

When To Feed Hermit Crabs

When it comes to feeding frequency, you should feed your hermit crab every day.

It’s best to feed them in the evening or at night when they are most active.

You should also make sure that you only feed them what they can eat in a single day, as any excess food can attract pests and other unwanted visitors.

Additionally, it’s important to vary the type of food you feed them, to ensure they get the nutrients they need. 

It’s also helpful to monitor your hermit crab’s food intake.

If you notice that they are not eating, it could be a sign of a health issue and you should take them to the vet.

Finally, it’s good to note that hermit crabs can be very picky eaters.

If they seem to be avoiding a certain type of food, it’s best to switch it out for something else.

You should also make sure to provide them with fresh food and water every day.

With the right diet and nutrition, your hermit crab will thrive and be healthy for years to come.
