 One of the biggest concerns when buying hermit crabs is early death due to PPS or Post Purchase Stress. The term PPS has been used commonly for many, many years in the hermit crab community. PPS is blamed for unexplained deaths of new crabs. The physical stress occurs mostly PRIOR to your purchase and how many of your new crabs die unexpectedly relies on how much stress was inflicted prior to purchase. The act of harvesting and shipping hermit crabs is very stressful as the crabs are denied humidity, food, water and warmth for long periods prior to shipping and during shipping. They mostly arrive at pet stores dry, hungry, dehydrated and sometimes cold. The last crabs harvested before shipping will be less stressed and more likely to survive. Naturally the opposite holds true for the first crabs to be harvested. Often it takes a period of time for the stress and dehydration to catch up with them but it does and the hermit crab dies. Sometimes it’s a week, or a month but it could take longer. Gill damage from dry air (lack of humidity) can be a slow painful death for a hermit crab. |
