nope! most people own hermit crabs and have them in tanks with sand.
first the hermit crabs mothers lay eggs then the eggs hatch and as soon as the eggs touch salt water, they burst open intobaby hermit crabs. Then they arelarvae. Then they grow in to adults and find a shell to live in.
No, nor the other way around. One breaths air, one breaths under water for their entire life.
Because everything dies, it's the circle of life
A hermit crab can die at any time during their life, however, it is known that crabs live anywhere from 30-50 years in the wild. Carol of Crabworks has had her crabs, John and Kate for over 30 years.
Hermit crabs can live 10+ years if you take good care of them!
If you treat crabs right they can live up to 20 years old. Most live ten
Hermit crabs can mate many times throughout their life. Hermit crabs can live to be 50+ years old in the wild and mate the whole time.
They only need a friend (of the opposite sex) to breed. Otherwise, they happily lead a solitary life.
I say about 15 Yrs if you treat them real well.
Hermit crabs live in the Caribbean so they need 70 - 80% humidity and 70 - 80F temp. Hermit crabs are VERY social so buy at least 2. one gallon of space per SMALL hermit crab. The substrate that is recommened is coconut huck fibers, so they can dig in it. also add some sand in a corner or half, The substrate should be able to cover the biggest hermit crab twice (so they can molt research what molting is IMPORTANT!) Hermit crabs are known to climb trees (They can drown in water!) so have something for them to climb on and something to hide in. Hermit crabs are scavengers so feed them fruits and veggies (change food daily). They also need DISTILLED WATER for them to drink tap water will blister their modified gills. And SEA salt water for them to bath in to heal, table salt will also blister modified gills. ALSO. . . TO LEARN MORE TO INCREASE YEARS OF HERMIT CRAB LIFE. . .

At petsmart you can buy your own hermit crabs for about $6.00 each. Mine last for up to 14 years so far. They are really amazing pets to keep and low maintainance. But keep in mind that they stink, so that means that you"ll have to take good care of them if you want them to live a long healthy life.
