How to Build a Fountain for a Hermit Crab

Hermit crabs are seaside land dwellers. So while they need a water source in their habitat, the source should not be too deep because hermit crabs can drown. Because moving water will remain fresher and be more natural for your pet crab, creating a small fountain, or really a bubble dish, in your crab's aquarium will make for a nice habitat.
