Best Hermit Crab Substrate Buying Guide

Hermit crab substrates are available in many different forms, including sand, forest bedding, or a combination of both sand and forest bedding.

Sand is a good choice of substrate for your hermit crab since it is what they would have in their natural habitat. A sand substrate is easy for crabs to burrow into and provides them with a healthy habitat.

Forest bedding substrate is typically made up of shredded coconut fibers. It retains moisture well and provides a healthy eating and burrowing environment for the crab.

You can also go for substrates that combine both sand and forest bedding. They combine the advantages of both sand and coconut fibers to make a healthy substrate that is great for your crab.

Substrates that are hard to burrow, lack moisture, or are too rough are not good for your hermit crab. Avoid substrates like gravel, pebbles, potting soil, and wood shavings.

  • Pick the Right Depth of Substrate – Your hermit crab will need a substrate that is deep enough for them to burrow into. This means that the proper depth to use will depend on the size of your hermit crab. For large hermit crabs, go for a substrate that is approximately 10-12 inches deep. This will be deep enough for the crab to burrow into and molt and provide them with enough protection. Always go for a substrate depth that your hermit crab can burrow into up to 3 times their size.
  • Go for Moist Substrates That Have a Soft Consistency. – The best substrate for your hermit crab is one that is able to retain moisture. Moisture creates the right level of humidity in your crab tank and creates the right texture for digging and burrowing. Dry substrate does not hold up well to tunneling and will make it hard for your hermit crab to dig into it. This is why you should avoid using coarse, pebbly, and dry material such as gravel. The level of moisture in your substrate should be just moist enough to build a sandcastle with but not too moist that it is soggy. Mixing sand and forest bedding substrate gives you the perfect moisture and texture of hermit crab substrate that your hermit crab can easily dig into.

Frequently Asked Questions (FAQs)
