Proper care is essential to keeping your hermit crab healthy and happy. These fascinating creatures require a warm and humid environment, with temperatures between 75-85°F and humidity levels of 70-80% to prevent dehydration. A glass tank with a secure lid works best to maintain these conditions. The substrate should be a mix of sand and coconut fiber, deep enough for burrowing, as hermit crabs molt underground to grow. They need access to both fresh and saltwater, treated with dechlorinator, and a balanced diet of fresh fruits, vegetables, protein sources, and calcium for strong exoskeletons. Providing multiple natural, unpainted shells is crucial for their growth and protection. With the right care, hermit crabs can live for many years, making them a long-term commitment rather than a temporary pet.
