The Ultimate Guide to Setting Up a Hermit Crab Home


Hermit crabs are fascinating creatures and make great pets. But before you bring one home, it is important to set up a proper habitat for them. In this guide, we will walk you through the steps of setting up the perfect hermit crab home, including tank size, substrate, decorations, and temperature and humidity levels.

Tank Size:

Hermit crabs need ample space to move around and explore. As a general rule, you should provide at least a 10-gallon tank for one or two small hermit crabs. For larger crabs or more than two, a larger tank is necessary. Make sure the tank has a secure lid to prevent your crabs from escaping.


Hermit crabs need substrate that is both comfortable for them to move around on and provides a source of moisture. A good option is coconut fiber, which can be purchased at most pet stores. Fill the bottom of the tank with a few inches of coconut fiber, then use a spray bottle to mist the substrate daily to keep it moist.


Hermit crabs love to explore and climb, so it is important to provide them with plenty of hiding places and climbing structures. You can use live or artificial plants, driftwood, and rocks to create a natural habitat for your crabs. Make sure any decorations you use are safe for your hermit crabs and won't harm them if they climb on them.

Temperature and Humidity:

Hermit crabs are sensitive to temperature and humidity, so it is important to keep these levels consistent in their habitat. The ideal temperature range is between 75-85 degrees Fahrenheit, with a humidity level of 70-80%. You can use a thermometer and hygrometer to monitor these levels and make adjustments as necessary.


By following these steps, you can set up the perfect home for your hermit crabs. Remember to provide enough space for them to move around, comfortable substrate, plenty of decorations to explore, and consistent temperature and humidity levels. Your hermit crabs will thank you for creating a safe and happy home for them to live in.
