Reasons why you should buy a Hermit Crab
relatively, quiet pets (some chirping... which is actually really cute)
good for people who have animal hair allergies (like me)
Don't take up a lot of space (Only the tank size and supplies)
relatively clean ( except when the little suckers bury there food)
Besides initial supplies they are pretty inexpensive (buy more sand/eco-earth ever several months, food, shells)
I want to have people to chat about something they love
Please note that even though hermit crabs are "low maintenance" they need specific needs and love and are not "throw away" pets. Make sure that you have done more research and are really sure you are willing to take on your little friends
