I'm not trying to argue with you Gary, just trying to learn what the differences are. I swear I see two distinct shape of tentacles on those pictures, the (for lack of a better word) "main" tentacles which look like those of a haddoni, and the longer looking ones along the rim. So I'm guessing the two "shapes" of the pizza anemones are different shapes than these? Bear with me, I've only seen fleeting glimpses of pizza anemones and I've never ever seen tapetum so I wouldn't know what are the "differentiating characteristics" are, of either.
