Hermit Crab Sand Substrate

(in stock)


  • Won't cling to crabs like calcium carbonate "sand"
  • Mimics sand most land hermit crabs find in their natural environment
  • Promotes natural tunnel digging and healthy molting

This sand substrate is perfect for your land hermit crab habitat. Unlike the calcium carbonate "sand" often sold as hermit crab substrate, this premium blend of natural sand, coconut fiber, calcium carbonate, sea salt mix, and probiotics (beneficial bacteria) is the superior choice for healthy crabs. The silica sand packs well and the coconut fiber helps retain moisture. Calcium and sea salt replicate the exact sand hermit crabs find in their natural environment. And the probiotics help maintain a clean habitat.

Hermit crabs are natural diggers. They dig to hunt for food and when it is time to molt. It is very important to fill your crab's habitat with enough moist Hermit Crab Sand Substrate for molting. The deep moist sand protects your crab during the molting process and prevents dehydration, which is vital for your crab's longevity. 6-lb bag.
