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.

The guide is now done! Woot! Hope it helps anyone who needs it.

Awesome job, and beautiful pictures. Very helpful guide. I just learned what some shells look like to match the names of shells I have heard mentioned on posts here. Thank you...your hard work is appreciated. [smilie=clap.gif]

Awesome! This was very much needed! Thanks Mac!

Thanks so much! That is really nice, i identified a lot of my shells from that! ^_^

Thanks for the beautiful pics and shell guide! All my PP's love Turbo shells. I actually have one PP that is still in the Haition Tree Snail Shell that he came in from the pet store, and he seems to have some balance problems with it. It's kind of funny because he just tumbles backward so easily, but I think he might be happier in a turbo. I am always still amazed at how beautiful these natural shells though.

As a new crabber I am finding this guide extremely helpful for my crab-journal keeping. Thanks so much!

Disliked by most hermit crabs ( they will move into another shell if such shell is more comfortable ) :

Dolphin turban (Angaria delphinus)


Fig shell (Ficus gracilis / F.subintermedia) & Harp shells (Harpa sp.)


Juvenile spider / scorpion conches (Lambis sp.)

Mac,
you should keep this updated if you don't already!

How do you suggest to do this? This guide isn't perfect (never will be) but crab's tastes don't exactly change during trends.... or seasons....are thick heels or thin heels in this year? Know what I mean?

On that note...added Zebra littorina shell for Es - pic from jesspark. It should be noted that these are pretty much impossible to find for sale. They are native to the E's home land though, and seem to be a popular choice. Your E might arive in such a shell.

I meant, keep the data collected amounts higher instead of having the ones that have say 100 hermit crabs in that type of shell take the ones that have 1000 hermit crabs in that type of shell.

I think the results would be generally the same, even if I did get more data. (which is no easy task btw, the information in this thread is the information members gave me.) Since this much interest was shown by the members, I am assuming that the amount of results here are also enough for the members. They are both equal - what was put into this by you, and what was put out by me.
