hermit crabs i guess
It depends on the gauge. Hermit crabs don't tolerate powder fine sand, it needs to be sugar sized granules.
nope! most people own hermit crabs and have them in tanks with sand.
Sand is better so they can dig.
no
Empty snail shells.
Hermit crabitats can have sand or coconut fibers, for they both are good for burying under.
No, for the substrate you can have coconut fiber. I have half of that and sand.
First of all, sand crabs are not hermit crabs. Sand crabs are usually tan, white, brownish, or other flesh-like colors. If you catch one, let it go--They need water.
Crabs, birds , turtles , sand fleas , hermit crabs, sand dollars , and a lot of other animals in the sea to ;)
Colored sand is harmful to Hermies because of the dyes
Land hermit crabs don't, they put them on damp sand at low tide, when the tide rises it carries the eggs away.
