No. Gravel of any size is not adequate for maintaining a burrow underground. Playsand from a hardware store is cheap, and crabs are able to tunnel in it. Make sure it's wetted to "sand castle consistency" and deep enough for the crabs to dig under.
It depends on the hermit crab but I would personally say just to be careful No the big one might hurt or bully the smaller crab.
a hermit crab can be from 1cm - 17.5cm in length!
The land hermit crab has a big claw and a small claw. The ocean hermit crab's claw's are the same size.
If it is a hermit crab, then it is like any other hermit crab, so just take care of it as you would to a regular hermit crab :)

When a hermit crab outgrows its shell, it will move into a larger shell.
Answer: The shell would have had to have it before the hermit crab moved in or something got stuck to it.
They cannot live with a land hermit crab because land hermit crabs live out of water so the fish would die (as you know) if it is out of water.

Sand, or fine gravel on the bottom of an aquarium, or a screen cage is ideal. You need to keep the cage temperature at least at 72 degrees Fahrenheit. The humidity level is best a 70%. The habitat for you hermit crab should have a moist warm feel, this will keep the gills of the hermit crab in check. Keep a spray bottle of fresh water handy and periodically spray your hermit crab habitat with it.
