I.D. on anemone

[hockey nut]

I was just wondering if there was a site with pictures etc so I can try to ID an anemone. I bought this 1 little guy to see what it would grow out as. I've never seen one in any of the stores in town for sale. I now have five as they seem to be happy splitting only one every few months. Thay are about 3" x 2" with clear stocks with very green mouths and face with green and purple fingers. Very nice. My clowns love them. Just curious if anyone has seen these before? Sorry no pics. Thanks for the help. Cheers :0)
