Where Do Hermit Crabs Live: A Guide to Creating a Perfect Crab Home

As pets, hermit crabs live in tanks that have to be adjusted for the proper temperature and humidity. This is to imitate their original habitat in the wild, which is close to the shoreline where they have access to both land and water.

Choosing a Hermit Crab Tank

Introducing hermit crabs to your home is a great way to add excitement and fun to your life, but be sure to plan – hermit crab tanks require a lot of space and proper setup. Choosing the right hermit crab tank is essential for a happy pet. 

The Ideal Tank Size

A larger tank is always better than a small one – adult hermits can live in tanks up to 10 gallons, but the more space they have, the happier they will be! Add some floating plants and an escape hatch to ensure your hermit crabs never feel caged.

Tank Material

The tank should be made from a transparent material so you can watch your crabs at all times. A hermit crab tank needs plenty of hiding spots where they can relax and feel safe. 

You also need to provide a place for them to climb out of the water – this can be a piece of wood or a nether part of the tank. It should also have a moist environment, as an overwatered crab will quickly develop fungal infections.

New vs. Preowned Tank

When it comes to choosing a new or preowned tank, there are a few things you need to keep in mind. 

Prewired tanks can be cheaper, but they may not always be as spacious or well-made as those already installed. Moreover, if there are any leaks in the tank, these could lead to water damage and possibly even algae growth. 

In contrast, new tanks are much easier to clean and maintain – you don’t have to worry about algae or nitrites build-up. This is essential for anyone with pets or children who might put their hands inside the water tank!

What Pet Hermit Crabs Need in Their Cages

What hermit crabs need in their cages includes water, food, and a substrate (or bed) that meets their specific needs. Please ensure the enclosure you provide is of the right size, clean, and free of dirt and debris. Hermit crabs should never live in dirty conditions – this will only make them sick and unhappy.

The Best Substrate for Hermit Crabs

Hermit crabs are fascinating creatures that require a specific substrate to survive. Make sure to choose the right one for your crab by researching different options and determining which is best for your crab. 

Sand is a popular choice because of its resistance to moisture and ability to hold it well. If you provide your crab with amphibian bedding such as moss or sponges, ensure they are dampened before putting them in the enclosure so the crabs will eat them! 

Crab food can also be used as a substrate; place small amounts on top and allow the crabs to feed from it. Hermit crabs are active creatures that need plenty of room to run and play, so be sure to provide them with a spacious enclosure.

How To Prepare Hermit Crab Bedding

Preparing hermit crab bedding is an essential part of hermit crab care. The substrate must be rigid and solid so that the hermits can lay their eggs on it, and the fresh substrate should be added every few weeks to keep them happy and fed. 

Some popular substrates for hermit crabs include coconuts, live plants, and even bark! You will need to water the bedding regularly if you use a living substrate; otherwise, they should not require too much attention. 

Ensure the bedding isn’t too wet or dry – a little moisture is okay, but excessive moisture will lead to problems such as fungus infection.

How Much Substrate Does a Hermit Crab Need?

If you are unsure about how much substrate your hermit crab needs, it is best to set some aside for them. A hermit crab needs a moist substrate to live on – in the form of sand, mud, or coconut husk. 

The amount of substrate a hermit crab needs will vary depending on its size and activity level. Hermit crabs love to live in colonies, so provide plenty of space for them!

Water Bowls and Hydration

Hermit crabs need plenty of water to survive, so providing them with a water bowl is essential. Make sure the water bowl is filled regularly and offer fresh food. Also, make sure your aquarium is big enough to accommodate them!

Climbing Toys

Climbing toys are essential to any hermit crab’s environment – they help the crustaceans stay active and climb around to find food or new shells. There are many different types of climbing toys on the market, so it is hard to go wrong. 

Whether you’re looking for a small toy that will fit on your desk or something larger that can be placed in your hermit crab’s home, there is a product out there perfect for you!

Hiding Spots

Hiding spots are an essential part of hermit crab life. They use them to escape danger and to relax. Some hermit crab species even move into swimming pools! So, be creative and think about where in your home you can put some exciting hiding spots for your hermit crabs – it will make them feel safe and comfortable!


Hermit crabs love living near plants – they find them an excellent place to scavenge food, water, and shelter from enemies. This means that keeping some tall plant or succulent by your hermit crab’s hiding spot is sure to be welcomed!

Plants offer plenty of benefits for you and your hermit crab – by providing them with shelter, food, and water, they’ll be healthier overall.

Humidity and Temperature for Hermit Crabs

Hermit crabs need high humidity and temperature levels to survive, so make sure your home is at the right temperature (around 75 to 85 degrees Fahrenheit) and humidity level (between 70-80%). 

To attract them, they set out food items like fresh fruit or vegetables inside their shelters. Make sure your home is warm enough for hermit crabs, as they are cold-blooded creatures.

Maintaining Humidity

If your home is not humid enough, you can buy a hermit crab humidity meter to measure the moisture level in the air or install an amphibian vaporizer. They can enable tolerate deficient humidity levels.

Can Hermit Crabs Live Alone?

Yes, hermit crabs can live alone. However, they may get lonely if left alone for too long. Providing a large enough habitat is essential, so the crab doesn’t feel crowded or stressed. 

If you ever notice any changes in behavior or appearance, take your crab to the veterinarian! And as always, feed your hermit crab regularly to remain healthy and strong.
