What will happen if your hermit crab shell brakes a little?

They say that a drop from about 3 feet can kill your hermit crab. If you dropped your hermit crab the first thing you should do is see if it's dead. It's body will look droopy and a dead hermit crab can start to smell like rotten fish. If your crab happeneds to still be alive but it's she'll is completely crAcked then gently scoop it up and put it into its cage with a bunch of shell options so they can pick a new shell.

What happens to a hermit crab's shell when it is molted?

Answer: It is eaten by the shedder for calcium to harden the new shell. The parts that remain (if uneaten) are quickly moved away from the lobsters' burrow so as NOT to attract predators. Other sea creatures will quickly consume shedded lobster shells, so you will never find a shedded lobster exoskelaton on the beach.

Do hermit crabs need a towel over their cage?

No, they don't unless there is a problem and your hermit crab has chosen to surface molt. In that case, he needs darkness and the best thing to do is give him a hidey such as a cocohut or other shelter so he can keep himself in darkness. Never ever disturb a molting hermit crab if it can be avoided. if a crab does surface molt, it is vital that you section him off from any other crabs you may have. This includes keeping them from being able to dig down under a barricade, as a molting crab gives off a very enticing smell (which is not an issue when they bury to molt) which may attract other hungry hermit crabs who will steal the shed exoskeleton of the molting crab who needs to eat it to regain strength. The newly molted hermit crab is also extremely soft and vulnerable, and could also become a target of another hungry hermit crab.

Do hermit crabs molt?

possibly, but most likely no. the outside should crumble/break/crack, allowing it to come out.

Another view: Your pet hermit crab should molt under the substrate (sand, or Eco Earth, NOT calci sand, which hardens like a rock when it gets wet and dries, never use as a substrate. put in their food dish instead). There are occasions when the hermit crab will surface molt, but this is not normal. Most often there is not appropriate substrate available (as in having only gravel, which is NOT hermit crab friendly, they need sand) or the crab is unduly stressed. There are some videos of hermit crabs surface molting on YouTube, if you are curious, do a search and watch those.

A hermit crab should never be disturbed when it is molting, never ever dig up a burrowed hermit crab. Molting can take a couple of weeks up to several months. Just keep the tank temperature and humidity in proper hermit crab ranges, change out the food and water dishes regularly, and leave them alone. They need darkness to trigger the molting hormone. Molting is their most fragile time, and they can easily die if stressed or disturbed too much during molting.

When do hermit crabs shed their outer skin?

hermit crabs never actually live with their parents. the female carries the eggs until they are ready to hatch and then cast them off into the sea. they hatch in the water and live as free floating plankton for a while, before getting on land and finding a shell, quite possibly nowhere near their parents.

Can a hermit crab have babies in captivity?

No, unfortunately they can't... Hermit crabs lay their eggs in the ocean, they are born without shells, and eat plankton. If you have a very large aquarium, and can manage to make a mini-saltwater ocean inside as well as dry land, it could be possible... Remember that the ocean must have a proper amount of salt! (table salt is harmful to hermit crabs too...)

Why does my hermit crab never come out of his shell?

The conditions may not be right for the crab.

Make sure the humidity levels are at 70-80% and that the heat is at about 75-80 degrees.

Sometimes though crabs will stay in there shells for a long time to de-stress from being moved from the pet store to your house. Some crabs take months to de-stress and other only take a day or two. Your crab may also come out at night while you're not around.

How do you know if a hermit crab is hungry?

Try to handle your crabs as often as you can. Let them walk on the palm of your hand, make your hand flat and stretch out your hand, so no excess skin is there for the crab to picnch on if he gets scared.

Play with your crab, let them walk around on your bedroom floor, but watch them carefully. You can also hand feed your hermit crab, if you want to buy the kit, it is at
