I.d.?

I was fishing last week and reeled in a piece of plastic with 9 of these guys on it. Not sure exactly what they are. Can anyone help?

They look like some species of rock anemone to me. Many species never make it into the aquarium trade, either because of collection difficulty or low demand (let's face it, we all like the PRETTY things). Where were you? At first glance they look like certain temperate anemones I've seen, but I have no real way of knowing.
