In years gone by hermit crabs were almost considered a throw away or disposable pet as not much was known about how to care for these lovable little critters. However as zoologists began to study the creatures in their natural habitat they were amazed to find that hermit crab life expectancy was good to say the least. Enthusiasts called “crabbers” began to realize that if they could recreate the hermit crabs surroundings contained within a captive environment, then there was a very good chance that their pet would live a long and happy life as it does in the wild.
It is a well documented fact that a hermit crab life expectancy can be upwards of 30 years plus and it is possible for your crab to live this long in captivity with a little T.L.C and attention. Therefore, as long as you get the basics right then there is no reason at all why this cannot happen. So what are the basics?
The right conditions
You need to remember that hermit crabs originate from tropical climes, so they are used to heat and humidity. So your tank or aquarium needs to be hot and humid. Aim for around 72oF and 70% humidity. This can be controlled by means of a small heater that you can get from any reputable pet retailer. As for the humidity, try purchasing a natural sponge, moisten it and place it in the tank. Another alternative is a water mister, as this will work just as well. Doing these few things will almost certainly prolong your hermit crab life expectancy.
Variety is the spice of life
They say that variety is the spice of life and in order to maximize your hermit crab life expectancy even more, you need to give variety both in your crabs’ diet and your crabs’ home. Hermit crabs are by no means fussy eaters and will eat just about anything, so it is okay to feed them human food. However, try to keep their diets varied with fruit and veggies and tiny amounts of meat and fish. Also you may want to integrate this with manufactured crab feed, in order to make sure that it receives all the nutrients it needs As for their homes, variety is also the order of the day! As they grow they discard one shell for another, so it is a good idea if you want to keep your crab happy and content, to make sure you have shells of various sizes and openings. If your little buddy does not have enough choice then he will probably remain in the shell that he is in, even though it has gotten way too small for him. This then puts un-necessary stress on the hermit crab.
Friends, friends and more friends
You may or may not know that hermit crabs are incredibly social creatures and are not at all like the name suggests. In fact, they thrive in small groups or colonies. Therefore purchasing one solitary hermit crab is like giving it a slow and painful death. Your hermit crab life expectancy would increase if you gave your crab another couple of buddies to hang around with.
Doing these simple things and getting the basics in place would ensure that your hermit crab life expectancy would be a long and fruitful one.
