Questionok so you where saying its bad for hermit crabs to live alone is three enough? or do i need more? also what kind of salt should i use for making salt water
AnswerHello, Yes they hate to be alone they live in very large(100+) groups in nature three would be great... you could always add more later they are very easy to care for. You use aquairum salt for saltwater fish tanks avalible in petstores...don't let the petstore people tell you what you need thou they don't think crabs need salt water half the time when most types do and other types benifit from it
please see this page for more info there are links at the bottom of the page as well that will help you out
