I live near Morrill/Hostetter (SJ,CA).
A little info about my current crabs. This way, you'll know your crab won't be lonely

I have 12 PPs and 2 Es as of now.
Sizes consist of 2 large PPs (golf ball)
The other 10 are around the size of a quarter (some a little bit bigger, most are a little smaller than a quarter)
One of the Es is about the size of a nickel
The other E is about the size of a dime
Overall, I carry small hermit crabs. Except for the 2 large PPs of course. I have room in my tank for only small ones. Quarter size or smaller (or slightly bigger). There's plenty of hiding and climbing spots in my tank. If you're interested, I can show you an image of my tank.
