aren't there some species of porcelain crabs that use a host anemone and some that don't? how can you tell the difference? is it considered acceptable to keep the anemone one without an anemone? thanks.
 
As far as I know, all the Porcelain crab species are commensal with an anemone in the wild. They really need the anemone to feel safe.
 
I've done some reading and the Petrolisthes spp. Porcelain crabs don't live on anemones and therefore don't need one.
 
This is a case where common names confuse the situation. People often mix up porcelain and anemone crabs. They are both filter feeders and they are both reef safe. They are of a similiar size but they are not the same thing. I've had both:

I have 2 anemone crabs without an anemone and they're perfectly fine. They stay in a little crevace in a rock during the day and venture out in the evenings.

Of course, my LFS sold them to me as a unique coloring of porcelain crabs but I knew what they actually were.
