Crushed Crab and Lobster Shell

In the wild your hermit crabs would find this on their own — now you can bring it straight to the tank.

A natural, mineral-rich source of calcium and magnesium — two essential nutrients hermit crabs need for a strong exoskeleton, healthy molting cycles, and overall vitality. Finely crushed for easy eating and digestion, this wild-inspired supplement mimics the mineral-rich components hermit crabs naturally seek out in nature.

Orders $35+ ship free. Orders under $35 ship flat $4.99 — no surprises at checkout. We cover any extra shipping cost so you can focus on spoiling your hermies. 🦀
