As hermit crabs grow and increase in size they need to come out of their shell in order to find a larger shell to live in.
no/yes
do hermit crabs perfer to have some light during the night or per darkness?
Well, most hermit crabs do not come out during the day, or when they know you are watching them. to see if they are alive, carefully put your fingewr nail on there claw, or blow on them. If they move it, than they are ok. If it is very stiff, they are still ok. If you can move there claw, yourself, and it is very wiggly, they are not usually alive.
with their legs ok but they walk with their legs bending forward and back, which is different from other crabs as other crabs bend side to side, hope that helps
a hermit crabs live 3-4 years t the most but its ok to live longer
Hermit crabs are nocturnal, so you might not see him/her playing around. If your hermit crab is inactive when you pick him/her up and/or during baths, get some water into his/her shell (not a lot) and your crabby might come out. If you have the HBH soak & spray mist, that works well too. If that doesn't work, that's ok. As long as your crab doesn't smell like fish and moves a little (even opening his/her claw)
As long as shell is not damaged it is probably ok. If it is put some new shells in with it and let him select one when it is dark and no one around.
yes, if its just corn, no butter or seasonings. Hermit crabs can eat all fruits and veggies, but not acidic food like lemons and limes. They like SEA salted nuts, and try to avoid feeding them human foods like twinkies, fat, seasoned meat, exct.
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.

Stress, Lack of no food/water, Killed by another crab, Lack of friends (which means if they don't have other crabs in the tank, they'll be lonley and less active.) Old age, Tempature to hot/ too cold, too much misting/ too little misting, Falling dangerous heights, Attacked by bigger animals, and drowning from a bath.
