Rest in Peace, my little baby crab Hulk x
yeah I get itsoilentgringa wrote:#14. If you were taking them out and bathing them daily, they could have been very stressed out. Sometimes if they have survived a molt or two they are more receptive to handling once they've gotten used to you. Honestly its probably best not to play with them or handle them unless absolutely necessary. I know a lot of crabbers handle their crabs and take them out a lot but I feel like we look like giant predators to them and mine all run for cover when I approach. I am sorry for your losses, I know you did your best to care for them.
they had all molted relatively recently? My small ones molted at least once a month. Hulk had molted a few weeks before he passed. Sampson hadn't molted, but she was medium sized and when I bought her she was freshly moltedwodesorel wrote:When was the last time they molted? Have they molted at all since coming home with you?
HCADirectors wrote:What is Post Purchase Syndrome?
Post Purchase Syndrome (also known as PPS) is a catch-all term used to describe the many reasons why newly purchased hermit crabs will often suffer from health problems and even death. All hermit crabs are wild caught, meaning that they undertook a huge journey from the beach or forest where they lived at the equator to finally end up in your tank. During this journey they would have passed through many hands and many locations, which means there were many opportunities for something to happen to them. Even if the store you purchased them at had ideal conditions, the damage may already have been done before the store ever received them.
Symptoms include leg loss, lethargy, not eating, not responding, slowing down, sitting in one location for days at a time. Sadly, even perfectly normal crabs will sometimes be found dead with no warning. Hermit crabs have a way of hanging onto life for weeks after a life-threatening occurrence. The damage that caused the death could have happened weeks or months ago.
The threat of PPS is over once the hermit crab molts successfully for the first time.
What causes it?
We don't know much about hermit crab diseases and parasites, but it's likely that they do suffer from both. Because of the stress of their collection and journey, and the fact that they were exposed to hundreds (if not thousands) of other crabs from different locations and who were of different species, they could have been exposed to something they had no natural immunity to. Both diseases and parasites can take over a stressed immune system, leaving the crab unable to fight off the infection.
They could also have been seriously injured during their journey, with no way for us to know if they are hurt until it's too late. (Aside from broken limbs, which most hermit crabs recover from completely.) Some hermit crabs are able to molt and repair any major damage they sustained, while others end up too badly hurt or just do not have the strength to heal.
Another issue could be dehydration or starvation from not being able to obtain enough food or water during their time in captivity. With so many crabs being packed so tightly together, the competition for resources is high, and many pet stores don't offer proper food or water for them to replenish themselves. These types of deprivations can cause permanent damage, and a weak crab may not be able to eat or drink once it gets home.
Temperature and humidity are important for them to stay healthy. If they had been kept too cold or too dry for too long it could have caused permanent damage. Low humidity especially can severely injure their gills. Often times there's no way to find out what the conditions were or how long they had been kept that way before they got to the store where you purchased them. If crabs were shipped during winter, they may have frozen during transport.
Hermit crabs need to be able to molt. If they put it off for too long a certain hormone builds up in their system, and if it builds up over time for too long the hermit crab can die from it. Since we have no way of knowing how long it had been since their last molt, this could also be a cause of PPS.
And finally, captivity is probably very hard to adjust to. Some hermit crabs may not be able to make the transition from the open world they came from to the tiny glass tank that we keep them in. There have been cases of hermit crabs who seemed to sink into a depression and simply gave up trying.
There are no veterinarians for hermit crabs. There also isn't much research into their health. We can only guess for now what the actual causes are, but all of the above are very likely scenarios and would explain why so many new hermit crabs pass away even when given perfect care. The HCA is always on the look out for new research that could explain why PPS occurs and how we can treat it successfully, and we will update as we learn more.

If they hadn't molted in captivity yet, there is a very high chance that you did nothing wrong, and that they died because of what they went through during collection and transport. Even if they did molt, if it wasn't a good one and they were weird after, it would still be classified as PPS.
I actually tried to look at that and see! I couldn't see anything but to be safe I boiled all the small shells before putting them back in. He still would stay in one. He passed away, and now I urgently need a home for my one remaining crabSydthesquid345 wrote:Do you think thumper was taking his shell off because there were bugs of some sort? I know this probably not the case but it's always a possibility.
