Congratulations on your new hermit crab! These unique pets require proper care to stay healthy and thrive. Hermit crabs need a warm, humid environment with a consistent temperature between 75-85°F and humidity around 70-80%. They also need a variety of properly sized shells to change into as they grow. A diet of fresh fruits, vegetables, and calcium sources like cuttlebone is essential, along with dechlorinated water for drinking and bathing. Avoid painted shells and use a natural substrate like coconut fiber and sand deep enough for burrowing. With the right care, hermit crabs can live for many years—some even decades!  This website and the links at the bottom of the page will help you to take care of your new pet!
