Can you ID these anemones

[Quinster]

I didn't see the first one for about 6 months after I put the rock in, it never moved once since I saw it so I really didn't worry about it, then to my surprise about 3 years later I looked one morning as the lights came on and then there were two. They are about 1" each and just sit there waving in the flow, neither ever move even when I move the rocks around. Any help would be appriciated...
