I just bought the Cholla wood.
Ans the shells
The advice im most looking for is..
How should i place my cholla wood?
Are those shells sufficient for crabs their size ? (also a link to the crab sizing chart would be nice, i cant find it)
And the glass jar im using for a hidey, they like it, but should it be dark?
And the crabs are crawling in the cholla wood, will they get stuck/is that a problem?

Thanks for the help

(p.s) The Crab in the picture with the shells is popcorn, he's slightly bigger than the size of the two new crabs i bought, so hopefully that would be a good measurement as to if they will fit in the shells.
Any advice would be great

Good or bad
