HCA: Hermit Crab Association

Hermit crabs required high humidity, that humidity will cause any metal in the tank to rust. This could harm your hermit crabs. You can use plastic egg crate instead, it's pretty cheap and hermit crabs love to climb it

It's recommended you have about 10 gallons per crab, although if they are (very) small the 10 gallon will work for now. You can always find cheap tanks on Craigslist or Facebook marketplace. It doesn't have to hold water. For a second level you can use plastic egg crate (which you can find at every ...

My crabs sometime switch in the saltwater pool, I even recorded it.

I have a few tanks: 15g, 20g, 29g, 35g and a 100 gallon tank

Can you post a picture? Are the legs white and fade into brown? Sounds like one of my crabs, instead of white it's orange. There are tons of PPs that are brown/have brown pinchers (including some of mine)

I got mine as a Christmas gift when I was 7. My parent's were like "Oh hermit crabs! A pet that doesn't need a lot of work, they don't live that long. Sure you can have it!" now over 9 years later, I got 6 hermit crabs 4 of which are rescues between a 30 gallon and a 35 with a 15 gallon topper

I use a mix of EE and playsand, I use a bit more EE then what is recommended. Since I find it keeps the humidity better then 5:1 ratio. I use a lot of playsand since EE is pricey and more EE seems more 'natural' since hermit crabs spend most of their time in the jungle, not on the beach.

What I use is a sheet of plastic as the lid. It keeps in the humidity and can move easily, it's cheap and all you have to do is cut it to the right size.

You could put springtails in your tank, they eat mold. Just make sure there are no escape routes out of the tank.

Don't worry, that is just on of the hermit crab's (many) legs, it's not a worm. I believe it's function are, cleaning itself, removing poop, extra pair of legs to hold onto the shell, I heard somewhere they also clean and move eggs if it's a female. Most people call them 'alien legs' which is approp...

Pantry Moths suck, I currently have a infestation of them in my house (have no idea where their coming from, they seem to pop out of no where). They might be attracted to the lights in your tank (or the heat, I'm not a entomologist so I'm just guessing). You crabs will eat them if they get the chanc...

I love picture 4, he seems to be saying "One day, I'll be big enough to fit in here!"

If you do decide to get hermit crabs you should know they are a long term commitment. Hermit crabs can live for over 40 years. The oldest one in captivity is about 45 years old, and still crawling. Some have been recorded living between 50-70 years in the wild. Although it's rare for hermit crabs to...

I have 4 hermit crabs in the 35 gallon, but I also have a 15 gallon topper. At least 2 if not 3 are molting, the other one only comes out between 2 and 6 am before going underground for the day.
