::runs down to hermit crab tank::
::pulls out copy of book::
they still sell this book along with gardner's tree crab book from 1970.
as far as using beach sand, someone just brought up this topic at LHC.com, and i which made me think about that recepie for making your own "mineral rich sand." beach sand is safe to use in crabitats as long as it's clean, sifted, and baked in the oven at 300F to kill any bugs.
if i remember correctly, the suggestions in that book weren't horrible. i was amazed that they suggested using a tank for the purpuse of maintaining humidity.
The pretty shells you see them wearing in pet shops and other retail outlest are not those they would normally wear in the wild. The reason for this is for camouflage. No intelligent crab would crawl about the beach wearing a bright, colorful shell if he could help it.
Although wild crabs want to go unnoticed, our captive pets need not worry about predators. Thus for our own satisfaction we should dispay them in the prettiest shells obtainable. Aside from beauty, which is nonfunctional, the main consideration is the size.
i laugh at the remark that we need to make sure the shells are pretty to meet our own aesthetics. if you don't, you will kill your crabs!
