A Hermit Crab Introduction: Basic Hermit Crab Information

What To Do With Your New Hermit Crab

Don’t worry I was there once too. Your son or daughter sweet talked or begged you into buying a hermit crab. So you have it at home now and you aren’t sure what the heck to do with him now and now you are looking for some hermit crab information.

Hermit Crab Information InĀ  A Nutshell

You are not alone, trust me! Everyone who actually now finds pleasure in keeping hermit crabs, and I say crabs (because it is actually true they are more fun by the dozen) has been in your shoes. So here is your hermit crab informationĀ  in a nutshell, for those who are new to the animal and hobby of taking care of hermit crabs and also for veteran that just want a refresher course.


In order for Herman your hermit crab to stay healthy you will need to know of some temperature requirements he has. You new pet should never be exposed to temperatures that are lower than 72 degrees Fahrenheit. It could probably kill a hermit crab if he is exposed to temperatures lower than this on a consistent basis.

On the flip side of this you certainly don’t want to put him on the window ledge and bake him with the incoming sun beams. You will notice a brown liquid discharge and a musty odor if your crab is overheating.


Not only does your crab need an even temperature he also needs a constant level of humidity in his environment. You should make sure your crabs environment has a moist “tropical” feel because these crustaceans thrive in an environment where humidity levels are at least 70%. It is not essential to measure this everyday but you should definitely keep it in mind.


The majority of new owners of these little guys do not know that they have to lay down a substrate in the cage. I remember when I adopted my family’s first crabs that I didn’t even know that a substrate was, honestly! But luckily it’s pretty basic, it’s just a name given to the material you place on the bottom of the cage. Crabs love to burrow and your crab is no different this is why you need some substrate.

Sand is found in the crab’s native habitat so this is a favorite for many of these pet owners. But if you don’t want sand then there are many other options at your local pet stores.

Make Sure It Is Deep Enough

No matter what material you choose to use in the end just make sure that it is deep enough so that your crab can bury. You don’t want to make it so deep that your friends aren’t getting the benefits of the heater, and yes you are going to need one of these too.
