It could be a few things or a combination of them. Most likely the crab is stressed or sick. This can happen if it's by itself (hermit crabs live in large colonies in the wild), if it's tank environment is not suitable (you need 80 deg F, 80% humidity, moist coconut fiber or sand substrate, etc) or not getting the right nutrition ("hermit crab food" sold at pet stores often contains hermful chemical and preservatives), not the right kind of water (they need deep dishes of both fresh and salt water). Or he could have been attacked by another crab.
What else can I help you with?
What are you supposed to do if a hermit crabs shell falls off?
Give it another shell to switch in to
Dose a hermit crab fall completely out of its shell?
Hermit crabs can. It happens when the hermit crab is changing its shell and falls over or when the hermit crab is dead it slides out or falls out of its shell! Sadly they can't always get back in there shells and die.
Do you throw the hermit crabs leg away after it falls off?
You can if you want to, but you can actually keep it in there and let it serve as another food choice for the hermit crab.
Can a hermit crab drown?
YES! hermit crabs may have gills but they are modified meaning they need humidity (70-85%) to breath NOT water, so don't fill your hermites bowl with too much distilled water or sea salt water.
What herment crabs eat?
In the sea they eat small snails, dead fish, and anything else they find. They find most of their food by "smell" using their antennae. Crabs and lobsters will eat decomposing animals that really smell a lot. In captivity they can be fed on bits of fish or meat preferably fresh.
If the hermit crab's arm falls off is it dead?
No, it is not dead. Hermit crabs can grow back their "arms" over time, though claws missing can be harder to live without. Just make sure you give lots of new shells so they can molt (which is when the arm is grown back). Don't worry-this happened to my herm!
What if a hermit crabs eye stalk falls off?
Then it is more than likely blind in that eye and may need surgery, you never know...lol. Like i said it is probably blind in that eye and the reason it could have fell off is that it might be dehydrated or its cage is not as moist and humid as it should be.
What do you do with the hermits crabs leg after it falls off?
Nothing, The leg will soon grow back.
How do you take care of pet hermit crabs?
FlooringThe ground of a hermit crabs tank should include sand, a little dirt, rocks and broken coral pieces (all store bought only or can carry mites or diseases). Maintaining clean sand isn't really a problem because hermit crabs aren't really messy.2-3 inches or sand is required for burrowing of the crabs.HousingI have 6 healthy hermit crabs living in a ten(10) gallon tank. Size differences will not be a problem because hermit crabs get along well. It is highly recommended that your crabs have cage mates because in the wild there pack animals.Selecting a healthy hermit crabSome pet stores will allow you to hold or observe their crabs before choosing the one you want. Look for moving antenna noticing your looking inside their cage and if there running away from you. Look for a crab that is a bright red in color, no swollen limbs. If a pet store does not have a giant collection of empty shells in the tank, then don't buy any. Hermit crabs NEED extra shells to switch into and if don't have a big selection of them, are probably not healthy and may die due to stress. Avoid hermit crabs that are just hanging out in the middle or the cage unaware that anything is going on.DietHermit crabs will eat just about anything from tree bark to other dead crustaceans. This includes leaves (preferably dry and crunchy),peanut butter, popcorn, fruits, vegies, crackers, applesauce, nuts, grass ,fish(dead only), cereal and everything in between. MAKE SURE NOT OF THESE PRODUCTS CONTAIN BUTTER OR SALT BOTH CAN POISON YOUR HERMIT CRAB!!! Remove all food the day after you put them in for in the hermit crabs humid habitat they will rot quickly. All foods found outside should be cleans WITHOUT soap.HeatingHermit crabs come from a tropical environment so temperatures should stay around 70-83 degrees daily and night time temperatures should cool to around the high 60s to the low 70s.If your house is colder at night they make inferred bulbs so the animal can think its night because they cant see red and heats them up also it makes nocturnal viewing possible. Commercial goods like the hermit crab heater can be bought at pet stores. A UVA bulb is also required for sun rays.WaterHermit crabs do need oxygen as well as they need water. You may think they breath to get oxygen, but no, hermit crabs have gills like fish. Oxygen is assimilated through water in the bloodstream, so it is very important to keep the humidity in your crabs enclosure at least 60 as seen on a humidity gauge. A humidity gauge isn't required as long as your smart enough to know you sprayed their cage enough. I say this because humidity gauges are very pricey, 15$ for a small one. Fresh and salt water is needed in their cage for drinking and salt water transfers calcium and keeps limbs hard and healthy. KEEP A SPONGE IN EACH WATER BOWLS AT ALL TIMES. Without the sponges, your hermit crabs have a very larger chance of drowning. Sponges can be bought at most pet stores. Tap water requires conditioner to take chlorine out and other harmfull materials.HabitatHermit crabs need lots of different hiding spots especially for a colony of crabs in one enclosure. All pet stores that sells anything at all in the reptile region should cover this. Pet stores with this sell artificial and real little tree chunks with a hollowed center or for decoration many sell "hermit hotels", a tall "building" with a hermit crab logo with a welcome sign on the front. For my crabs I found in the aquarium section a sponge bob squarepants and squidward house which i put in their habitat. I found that with those, the windows are small holes which the crabs use to climb to the top of the house.Behavior and HandlingHermit crabs are very sensitive animals and have moods. All but one of my hermit crabs have let me hold them and the last one pinched me. WARNING:HERMIT CRAB PINCHES HURT!!! Their rough skin along with rigid edges on the inside of the claw, provide a very hard pinch. When they pinch its either you made them made or there in a bad mood. When I got pinched the little guy wouldn't let go and it took dipping him upside down underwater to get him off. NEVER TRY TO TAKE YOUR HERMIT CRAB OUT OF THEIR SHELL!!! The inner soft tail of the crab is their most sensitive part and the crab will fight to the death to stay in the shell. Rarely you can catch a glimpse of your crab out of there shell which they only do when they molt. I saw it myself and its an amazing sight because they come out for less than 5 seconds about once every two months. To hold your hermit crab place it on for hand flat and if hes in a happy mood he will come out and walk. You will notice the crab will walk around upside down under your hand. Make sure you catch him if he falls. Avoid walking around with your crab because that ticks them off encouraging pinching.
Are crabs warm or cold blooded?
Crabs are cold blooded animals, as their body temperature rises and falls with their surroundings.
What do you do if your hermit crbs big pincer falls off?
Nothing, he's probably molting, so don't disturb him!
Where should you take your hermit crab if you can no longer take care of it?
If you can no longer keep your pet hermit crab take it to a low tide beach and if you live near a beach where it came from its perfect i live in Arizona but mine is from the carribbean so i hope i wont get rid of it soon xD
