Calcium is often associated with bone strength and growth. But why do mystery snails need calcium when they do not have bones?

Yes, they don’t have bones but they do have shells. About 95 percent of their shells are made of calcium carbonate, hence they require enough calcium to maintain shell strength.

Much like other snails, a strong shell helps them protect their soft, vulnerable bodies from predators. Shells also keep their internal organs safe and always protected, so they can travel through the tank without worries. The more calcium they get, the stronger their shells become.

No worries, you can provide an adequate amount of calcium both from food and water so your pets can grow healthy.
