Rock Anemones??

[Aquatic Hamster]

I have these bright green critters growing among my zoanthid colonies. After a discussion on the zoanthid board the consensus was that these might be a rock anemone. They suggested that I should post here and see if people could confirm.

I'm not sure if what you have there is Epicystis crucifer or not. I have seen small ones that look similar to that, but time will tell. E. crucifer gets up to about 8 inches across. They are a very nice addition to a tank, in my opinion.
