This Preferred Shell Guide was created from the feedback of members from the hermit crab forums. The info was collected by myself but would not be able to be done without the input of you all. Thank you!
Every crab is different, however I've collected information on how many crabs are in certain kinds of shells, to conclude what shells are a favorite with certain species, and what are not. I hope this guide will help you having a better idea in what types of shells your crabs would like. Your one crab might hate one of these shells, but another of your same species might love it. Some species have more data collected then others, but you should still be able to find what you are looking for.
So without any further waiting, the shells under each species heading are the shells that the certain species of land hermit crab seems to like, most popular are listed first however all the shells listed have made the cut to be considered a preferred shell of that species.
