Fluker's All-Natural Beach Sand Substrate for Hermit Crabs – Coconut Fiber, Probiotics & Sea Salt Blend

Give your hermit crabs a habitat that feels like home with Fluker’s All-Natural Beach Sand Substrate — a carefully crafted blend of sand, coconut fiber, sea salt, calcium carbonate, and natural probiotics that replicates the natural beach environment hermit crabs need to thrive.

The coconut fiber component retains moisture to maintain the humidity levels essential for hermit crab health, while the sand texture encourages natural burrowing and digging behaviors — especially important during the molting process. Added probiotics help break down organic waste, keeping the habitat cleaner for longer between full substrate changes.
