Name that anemone

[Flipper1]

In my copy of Reef Secrets by Nilsen and Fossa, in the pages where a few crabs are identified (in the picture section), there's a particular crab that often transports a small anemone on its back. The anemone is identified by name with the crab's description.

However, my book is out on loan, and I need to know the name of the anemone so I can look it up and determine if it's okay to add to my reef. I've got three of them waiting for me at the shop.

Does anyone here know what the anemone is called, or be able to look it up if you've got the book? Thanks!

Thanks for the reply. Although I'm not positive, I don't think these are exactly what I have. The anemones have a good deal of green color to them, which fluoresces under the actinics.

I've got the anemones now. They're only about 2 cm. across with maybe 2 dozen tentacles. They're deep green, with the tips of the tentacles being red.
