maybe he is tired and wants to sleep.
However long they feel like it
You should not force a hermit crab completely out of their shell because they would rather die then be forced out of their shell But if you want to know how to make their legs and eyes and anntenue so they will walk around then you could try lifting up their shell or gently squirting them with a spritz bottle filled with dechlorinated
Hermit crabs love a large area with lots of space to play in and plenty to climb on an old aquariam tank is perfect for hermit crab/s
Yes, the hermit crab remains in it's (outer) sea shell/home when it molts. However, when the hermit crab molts it sheds it's old exoskeleton much like a snake sheds it's skin, pushing the old exoskeleton out of the sea shell, and forms a new exoskeleton. The new exoskeleton is soft at first and takes time to harden. The hermit crab's "tail and belly" section remains soft and vulnerable requiring a hard outer shell/sea shell for protection.
Hermit crabs need a shell because inside of the their shell is their soft tail or body. It needs it's shell because other hermit crabs can hurt or damage their tail or body that's inside of the shell. Hermit crabs will always be in a shell. The only time when they aren't in a shell is that quick few seconds when they change shells into a bigger one to grow. If your hermit crab is running around without it's shells there is something wrong with your crab. Go to the Mall of America (Nickaloden Universe) what ever you want to call it and ask the person why. I bet he can help you.
It will either stay out of it's shell or have a shell fight with another crab to take its shell. I do not recommend letting your crab have no shell for very long though, it makes them very vulnerable and stressed out making them a good target for other crabs to harm.
NO they don't because they they stay in shell
Hermit crabs are nocturnal, so it sounds like your hermit must have gone to sleep. Mine has slept for a week, once! If you get home and you find your hermit crab out of it's shell and looking see-through, then it has molted. Hermits usually molt on their 'birthday' but stay in their shells a while prior to molting.
because they have 2 legs inside their shell to hold on to the shell
Hermit crabs don't have a regular size because they grow, they don't stay the same size.
It could be because the shell is dirty, to small or searching for a new one. Hermit crabs are always in their shells. Hermit crabs will never leave their shells unless switching. IF your hermit crab is running around without it's shell there is something wrong with it.AnswerThis could be because it has outgrown its shell and is searching for a larger one. A tight-fitting shell stunts the crab's growth, making it easier for a predator to eat it. There is always lots of competition between hermit crabs for their shells. This could also be because the hermit crab is stressed out because of lack of humidity or temp not being right. The hermit crab is vulnerable without his shell so separating him from the others and providing him with tons of shells helps. You can even use the cup method and place the crab gently in a cup with a shell. This helps sometimes.
yes they do becuse if they dont the part that goes in the shell is very tender and soft and can get dameged very easy so its good to have difernt sized empty shells in the cage so the crab can change the shells when needed
