What Type of Sand for Hermit Crabs is Most Like Their Natural Habitat
An important aspect of caring for hermit crabs is understanding their natural environment and providing sand for hermit crabs that closely resembles their natural habitat.
What’s the best substrate to put on the bottom of your hermit crabitat? There are a few options that can work well, but it’s important to try to stick closest to what your particular species of hermit crab lives in, in the wild.

Understanding the Natural Habitat of Hermit Crabs
Hermit crabs are primarily found in tropical and sub-tropical coastal regions, particularly near the ocean and along the shoreline. They inhabit sandy beaches, mangroves and coastal forests.
When setting up a hermit crab habitat, it’s important to know the type of hermit crabs you have and where they originally come from so you can create a similar environment.
Example: there are differences in temperatures, humidity levels, and types of sand and substrate found in different regions.
Different regions inhabit different types of hermit crabs, and it’s important to know which type of hermit crabs you have. If you aren’t sure, check out my post on Types of Hermit Crabs with Photos here.
Example: Caribbean Purple Pincher hermit crabs are the most popular type of hermit crab found in the United States and Caribbean Islands. The type of sand found in this region of the world is different than other regions.
Characteristics of an Ideal Sand for Hermit Crab Habitats
Particle Size:
Choose sand with fine particles, as it allows for easier burrowing and digging. Coarse or rough sand can cause discomfort to your hermit crabs. And NEVER use pebbles or rocks!
Moisture Retention:
The sand should be able to hold moisture without becoming excessively wet or compacted. This is crucial for maintaining proper humidity levels in the enclosure. Too much moisture and humidity will cause mildew and mold growth, detrimental to your hermit crab’s health.
Chemical-free:
Whether you are buying sand or substrate from a store or gathering it from nature, there could be chemicals! Products that aren’t made for kids or pets could have harmful chemicals, pesticides or additives that could be toxic to hermit crabs.
It’s best to stick to safe products that are made and tested specifically for the pet industry. Make sure to read labels paying close attention to any possible additives or other ingredients that may be mixed in… and stick to products that are 100% natural.
Types of Sand and Substrate
Several types of sand are suitable for hermit crab enclosures. Let’s explore some of the popular options:

Natural Sand
There are many natural sand products found for sale in the pet industry. It’s best to purchase natural sand from two sections of your local pet store (or Amazon or other online retailer): 1) the hermit crab section or 2) the aquarium section.
Generally speaking, if it’s safe in a reef aquarium, it’s safe for your hermit crabs. BUT pay attention to the grade/size of sand particles. A hermit crab’s natural environment has a mixture of fine sand and small crushed coral particles. Don’t use rocks, pebbles, or large coarse sand.
There are some great and inexpensive Florida crushed coral natural sand products you can find in the aquarium section, a favorite substrate for marine tanks. Remember, if you have Caribbean Purple Pincher hermit crabs, they come from beaches where the sand IS crushed coral.
PERSONAL NOTE: I use a mix of Caribbean crushed coral fine sand, plus Hermit Crab Beach Sand Substrate, plus some coco-fiber mixed in. I like to keep the mix with the coco fiber just below the surface, with a nice clean 1/2″ spread of just sand on top.
Play Sand
Play sand, typically used in children’s sandboxes, is a common choice among hermit crab owners. It is affordable, easy to find, and has a fine texture that allows for comfortable burrowing.
However, play sand dries quickly and does not maintain moisture and humidity well. It’s also not a natural sand like calcium carbonate found along Caribbean and Atlantic Ocean beaches, made up of primarily crushed coral.
Depending on your climate, indoor temperature, other ways you maintain moisture and humidity in your habitat… you’ll probably need to add coco fiber or other type of sand so the substrate holds a little more moisture than play sand alone does.
Play sand is very economical, and easily found at your local big box or hardware store.
Coco-fiber Substrate (coconut coir)
Coconut fiber substrate, also known as coconut coir, is another option very popular among hermit crab pet owners. It is made from the husks of coconuts and provides excellent moisture retention. However, it doesn’t offer the same burrowing consistency as sand and may not be suitable for all hermit crab species.
For Caribbean Purple Pinchers, a mixture of fine sand and coco-fiber (3:1) makes a great simulation of what hermit crabs typically live in, in the wild.

Keep in mind, hermit crabs do not burrow and molt in the pure sand along the edge of the ocean, due to changing tides; they would drown. They typically burrow and molt a little further into a dryer area often with more trees and dense mangroves, seagrape or other coastal foliage. Purple Pinchers are a species known to live further away from the shoreline than other species.
Beach Sand
Beach sand collected from an actual beach will often contain contaminants including chemicals, washed up oil residue from boats and unwanted parasites.
Keep in mind, depending on where you collect beach sand, it could be exposed to things like pesticides (mosquito sprays) and weed killer chemicals, detrimental to hermit crabs in addition to other potentially harmful elements. It’s better to stick to purchasing reputable products that are specifically for pets and/or children.
Determining Most Suitable Sand Substrate for your habitat
To determine the most suitable sand for your hermit crabs, consider the following factors:
- Availability: Check local pet stores, online retailers, or specialized hermit crab suppliers to find the sand you need.
- Hermit Crab Species: Different species may have specific sand requirements. Research the natural habitats of your particular hermit crab species to find the closest match.
- Budget: Consider your budget and choose a sand option that offers a balance between quality and affordability.- Maintenance: Evaluate the ease of cleaning and maintaining the sand, as you will need to regularly monitor and replace it when necessary.
How to Prepare and Maintain the Sand Substrate
To prepare the sand for your hermit crab enclosure, it’s important to clean the sand thoroughly to remove any debris or contaminants:
1. Pour sand into a large bucket or empty tank, and use a hose placed into the sand on the bottom to slowly move any debris or contaminants to the surface, tipping the bucket or tank to let out large amounts of dirty water at a time. Rinse and repeat until water is clear.
2. If you live in a sunny climate, “bake” the sand in direct sun by using a large plastic bin and spread the sand out as thinly as possible, and place it on a table or above ground level (avoiding cats, dogs and other pets from getting inside).
3. Fill the enclosure with a sufficient layer of sand to allow your hermit crabs to burrow and dig comfortably. Not sure how many inches deep your substrate should be? Here’s my post with more information on How Deep Should the Substrate Be, here.
4. Monitor the condition of sand regularly, and use a small sand scooper by gently scraping over the surface, removing any waste or uneaten food promptly. Be careful not to disturb any burrowing or molting hermies!
5. Maintain the appropriate moisture levels by misting the sand with water regularly, and using a hygrometer to measure humidity levels.
Tip: sand should remain more dry than wet, as the areas where hermit crabs choose to burrow in nature typically are. But a daily misting is important to add some moisture, sometimes a little more and some times a little less will make your hermit crabs happy (they love misting and small water droplets, it’s a source of stimulation).
FAQ: Frequently Asked Questions
Q. Can I use regular beach sand for my hermit crabs?
A. Yes, you can use beach sand for your hermit crabs, but make sure to clean it extremely well before use to avoid any potential contaminants.
Q. How often should I change the sand in my hermit crab’s enclosure?
A. It’s recommended to replace the sand every few months or sooner if it becomes soiled or too compacted.
Q. Can I mix different types of sand for my hermit crabs?
A. Yes, mixing different types of or products of sand can be good as this can more closely mimic the natural sand environment where hermit crabs live in the wild.
Q. Should I provide a separate area with moist sand for molting?
A. There’s no way to force your hermit crabs to molt in a specific area, but you can make areas more enticing for them by keeping bottom sand substrate slightly moist, or doing a daily misting plus keeping a large surface area clear for burrowing.
Q. Can I use sand from my garden for my hermit crabs?
A. It’s never a good idea to use sand from a garden for pets, as it will contain contaminants and possibly parasites, insects, excrement and other elements you don’t want to introduce into your hermit crab habitat.
