Shell sizes

Post by Riceyandspicy » Wed Nov 28, 2018 6:36 pm

Most of my crabs have a shell size of 1-1.5 inches what would be the next shell size up?
I have 3 PPs and 2 prefer D shaped shells while only one is using a turbo shell.

I usually increase my shells by at least 1/8" up from the current largest shell. I also order a few shells 1/8" above that as well. Sometimes they go waaay bigger, sometime just a little bigger. Your smaller crabs can get the "crab me downs" from the larger ones.

To answer your question, your largest is a 1 1/2" opening. I would go with 1 5/8" for 1/8 over.
1 3/4" for 1/8 above that.

Those would be some pretty big crabs with 1 1/2" openings. I know a lot of people misjudge openings all the time when they order shells. It isn't so bad with smaller shells. Once you get to 1 1/8" openings and above shells can get pretty pricey.

Maybe I measured incorrectly like you said i measured the length of the entire opening, should I have measured just the crab?

Measure the widest area of the openings. Here's a link to the basic tutorial of how the Naples Sea Shell Company measures the hermit crab shells they sell.

They say to measure the length of the big claw. I just do my best to measure the shell opening and go from there. I'm my experience you can have 10 what you think are ideal shells and 1 that doesn't seem the right shape or size. They will pick that odd ball most times. Crabs are weird.
