Salt water probably the colorful rocks and stuff like that
Congratulations! No need to rename it. It's the same hermit crab. It molted it's old skin! This means your hermit crab is perfectly healthy and can grow! Make sure you have a slightly bigger shell though. Leave it alone until it walks around and is very healthy.
no
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.
She will drop them in water of any depth but there is no way for the average hobbiest hermit crab keeper to keep them alive, so it's a bit of a moot point.
Absolutely!
Hermit crabs molt when they feel the need to. Nothing is wrong with your crab if it hasn't molted. :)
you don't need to do anything a hermit crab will do it itself. if a hermit crab losses a leg it will grow back. it will grow back after molting.
It was to cold
Hermit crabs haveb modified gills which means they can't breathe underwater but need 70-80% of humidity and temp to keep their gills moist.
Hermit crabs do not bite, they pinch. When a hermit crab pinches you that means that they are intimidated and stressed out, and possibly hungry. In your crabitat there should always be fresh food available to your hermit crab so it does not starve.

I LOVE that question! hermit crabs have been abused for years! hermit crabs are tropical animals. thay need 1 gallon of space per hermit crab, they also need love and attention they have personalities too.
No, you need to make sure the hermit crab has enough food and water, the humidity and temp are where they need to be, has hiding places and climbing toys, and most importantly he has at least 2 other hermies with him. hermit crabs can die if they dont have any other hermies with them.
