Changed to a too-small shell

[Apoplexic]

Copy and pasting this from a Facebook group I'm also in because this is starting to concern me and I want as many different opinions as I can on it.

One more for the night. I just added about a dozen awesome shells thanks to one of our members, so it's a change-fest right now. However, my (now) third-largest just left a shell that was a bit too small for one that is totally too small, and I don't understand why - my immediate thought is maybe somehow I landed a Brevi and never knew it but I'm 99% sure she's a PP. What's up with her?

I watched her for a solid 20 minutes muck with it before she switched, and then after she literally flipped her old shell away and wandered into the hide - she's not coming back for it.

Update a few hours later - she is still in that shell. It did not feel modified as if by an Eccie (I checked them all, was gonna throw E-friendly ones almost on top of two that still won't leave their modified but painted shells :Z)...I just don't understand and am honestly slightly worried. I assume she must like it...but why.

Its a PP. Sometimes crabs just like shells with a tighter fit. I wouldn't worry, as long as she has options to change into a larger (a little more size appropiate) shell she'll be fine.

Facebook also told me that sometimes they will take a smaller shell before going down for a molt - this would be her first in a long time if that's the case. Either way I feel much better; it just really got to me when she did what was supposed to be the opposite behavior!

Thank you.

There are no hard and fast rules when it comes to crabs and shells. The best thing is to give them a selection of sizes and types and let them have fun. Keep in mind in the wild they may only ever end up finding a few good shells in their lifetime, or end up with hand me downs forever. I sometimes think we overwhelm them by giving them so many choices! However, when housing hermits together it is better to overwhelm so they don't set their sites on a tankmate's shell being better for them.

That's what was really getting to me - there were two or three sarmaticus shells just beside that one, including one that would have made her appear Tiny when she's borderline Jumbo. Instead she chose a smaller...forget the species of snail...D-shaped shell!

Crazy crabs.

Neither of my jumbo guys wants a proper sized shell. They have lots of options, and Agent K swaps shells on the regular. But neither one can ever fully get inside their chosen shells like the littles like to do. Everyone else from Large down to teeny all like to have shells they can completely retract into. I think as long as there are options in the correct sizes, don't stress if they don't pick a shell we think is the right size. Maybe she's just one of those girls that always runs around in teeny tiny yoga pants.
