I have a good amount of Hermit crabs that need new homes. Do I buy empty shells from a LFS or can I buy some fancy shells from a craft store as long as ther not treated or bleached?
to be safe, it's best to boil the shells in RO water for 10 min to kill anything that may be living in the shell. That's what I do for my expired snails.
I love seeing my hermits run around in bumble bee and nassarius shells.
