Water given must be de-chlorinated. Change daily.
Use salt mix that is for Marine Aquarium, do not use Table Salt.

Bathing them once a week is enough, too much will stress them. Water must be de-chlorinated, add a little salt. Do not immerse them totally into water.

Love your little hermit crabs. One time, I had 24 of them at once! They are neat and easy to take care of. Yours and their setup are very colorful. You may have just inspired me to get more of them.

Hi Megan,
I've only 6 hermit crabs but now I'm left with none! They each slowly pass away one by one after about 1 year! So sad!
