Negatory, definitely an anemone though they are quite similar looking if they can't be seen side-by-side. I have a ricordea florida and side-by-side they are quite different: the anemone actively grabs food while the ricordea does not, the nem's tentacles are much bigger, the ricordea hates bright light and the nem loves it. Here is a pic of the nem and the ricordea side by side at the same camera magnification and distance from the camera.
