Dropping of limbs is a very bad sign.

Causes of this are the following.

Stress
over-heating
too dry
over handling
improper tank conditions
improper diet
improper substrate
aggressive tank mates


At times of stress, illness or incorrect tank conditions a crab can drop it鈥檚 limbs. You may notice a crab looking
under the weather, and then further notice a leg or pincher missing.
Many times this is due to stress or injury. It may be a
battle wound from a fight in the tank or an injury from a fall or getting stuck.
Other times it is from a tank that is too hot or you disturbed a molter.
The best thing to do is to make sure the crab鈥檚 diet is rich with calcium and protein and watch over it. Another suggestion is a salt water bath to help clean the open wound and help it heal faster.

You will need to ISO this crab and make sure the tank humidity and temperatures are within the correct range and monitored 24/7 with the use of gauges. 75%-85% relative humdity and 76-82 degrees F.
Also make sure you provide both fresha nd natural oceanic/marine salt water in large pools and both waters are de-chlorinated. Fresh fruits, veggies, meats, fish and whole grains as food, never offering the same things 2 times in a row and food available 24/7

Sand and moist coco-fiber or a mixture of the two are the approved substrates aand a solid tank lid with lights is also another must.

Also each crab must have at least 4 extra shells available in the tank at all times of the proper size, shape and type, paying attention to the opensing size and shape as well.

GEL LIMBS
When it is ready and recovered strength it may start growing a gel limb, which will continue to enlarge until it is time for the crab to molt. Then that gel limb will turn into a new working limb, just a smaller version of the original and it may take several molts until that limb is back to the original size.

Just watch it's molting seasone will be over soon.

I worked with a lady who had some, they dont live very long %26 yes they do shed %26 lose legs. You need to change out the shells also. did anyone tell you that? b/c they will need bigger shells. I believe she started with 5 %26 within a year and a half they were all gone. And one out lived the others by a good 4 months. Sorry.

Okay. Make sure there's plenty of moisture in the tank, and a few shells available, just in case it wants to change.

They might be fighting.

Land hermit crabs have the potential to live MUCH longer than a year and a half, if they are cared for properly and they do not contact some sort of parasite or disease. Some crabs can live up to 20 years.

hermit crabs do that and if you have more than one it may be the others shedding and moving on in the new shell. keep a close eye though and all should be fine.
