Worm Castings

A crabitat staple your hermies will dig through — literally — introducing Worm Castings.

Naturally left behind by worms as they move through soil, these nutrient-dense castings are packed with calcium, magnesium, and beneficial microbes that support a healthy tank environment. Worm castings enrich your substrate, encourage natural digging behavior, and provide trace nutrients your hermit crabs will instinctively seek out.

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. 🦀
