You sure can, it would be best to sterilize it first. I suggest laying the sand out on a sheet and baking it in the oven for a bit. It'll kill the bacteria and give you a chance to remove any harmful debris.
either would work but i would say either sand or mix the sand and pebbles together
you can but you need to bake for 3 hours stir occasionally and strain sand out but try not to
yes you can also use coconut fiber, but stay away from chips and gravel.
Yes, as long as it is damp so when the hermie trys to burrow it can get back out.
Sand is better so they can dig.
hermit crabs i guess
pineapples can
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.
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.
I really don't think you shoulden't because hermit crabs aren't where expirensed with other crabs what i'm trying to say is that the other crab might try to take him out of his shell and eat him but hey what do i know i'm 10
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 ;)
