I don't like hermit crabs (except for the ones I caught myself in a bay in a kayak) and they always smell really bad and only like 1-2 years but in the wild they live 25! It stinks they don't live so long and it really stinks when they die!
I put them in the tank at work, with larger shells, since they were in tiny shells they all hoped out and got into larger shells! OMG that freaked me out!!! the body is like... WEIRD!!!! pretty cool how they check if anything is living in the shell, and then just kinda like jumping into a jump jet, they are in and out so quick!
they still smell! I was racing them all day at work!
