Hermit crabs are fascinating creatures that make for wonderful pets. They are easy to care for and provide endless entertainment with their unique behaviors and personalities. In this article, we will provide you with everything you need to know about keeping a hermit crab pet in 2023.

Getting Started

The first step in keeping a hermit crab pet is to set up a suitable habitat. You will need a tank that is at least 10 gallons in size, as hermit crabs require plenty of space to move around. The tank should also have a lid to prevent the crabs from escaping.

Next, you will need to provide your hermit crab with a substrate to burrow in. A mix of sand and coconut fiber is ideal, as it mimics the crab’s natural habitat. You will also need to provide a few hiding places, such as small caves or pieces of driftwood.

Feeding Your Hermit Crab

Hermit crabs are omnivores, which means they eat both plant and animal matter. You can feed your crab a variety of foods, including fresh fruits and vegetables, dried shrimp, and even commercial hermit crab food.

It’s important to provide your crab with a calcium source, such as cuttlebone or crushed oyster shells, to help keep their shells strong. You should also provide a small dish of fresh water and a dish of salt water for your crab to soak in.

Maintaining the Habitat

Keeping your hermit crab’s habitat clean is essential for their health and well-being. You should spot clean the tank daily, removing any uneaten food or waste. Once a week, you should do a full cleaning of the tank by removing all the substrate and cleaning the tank with a pet-safe cleaner.

You should also monitor the temperature and humidity levels in the tank. Hermit crabs require a warm, humid environment to thrive. The temperature should be between 75-85 degrees Fahrenheit, and the humidity should be around 70-80%.

Handling Your Hermit Crab

Hermit crabs are delicate creatures, so it’s important to handle them with care. You should never pick up a hermit crab by its shell, as this can cause it to fall out and potentially harm the crab. Instead, scoop the crab up gently with your hand, supporting both its body and shell.

It’s also important to give your hermit crab plenty of time to adjust to its new environment before handling it. Hermit crabs can be skittish at first, but with time and patience, they will become more comfortable with you.

Common Health Issues

Like any pet, hermit crabs can experience health issues. One common issue is shell rot, which is caused by bacterial or fungal infections. You can prevent shell rot by providing a clean, humid environment and ensuring your crab has access to a calcium source.

Another issue is molting, which is when the crab sheds its exoskeleton to grow a new one. During this time, the crab is vulnerable and may appear lethargic or inactive. It’s important to leave your crab alone during this time to allow it to molt in peace.


Keeping a hermit crab pet can be a rewarding and enjoyable experience. By following the tips outlined in this article, you can provide your crab with a happy and healthy life. Remember to always do your research and consult with a veterinarian if you have any concerns about your pet’s health.
