The Delightful World of Hermit Crab Diets

As hermit crab owners, we always strive to provide the best possible care for our cute little pets. One of the essential aspects of ensuring their well-being is offering them a balanced and nutritious diet.

It's crucial to understand their dietary requirements to provide our hermit crabs with a healthy and balanced diet that they would truly enjoy.

While hermit crabs can benefit from the calcium found in yogurt, it is not a recommended source of calcium or protein for them.

  • Cooked, unseasoned meats (chicken, turkey, or beef)

These calcium sources are a much better alternative than yogurt for the overall health of your hermit crab.
