I picked hermit crabs because I had one as a pet. Hermit crabs need to live near water because their offspring start life in the water. These offspring grow and develop in water to become land crabs. They also need a wide variety of shells around because they carry one on their back for shelter and protection. As they grow, they need access to larger shells. Food is another resource that hermit crabs need. The species I owned survived on a primarily fruit-based diet.
