True VS False Percula Clownfishes - How Can You Tell Which is Which?

We have heard some saltwater aquarists say that the difference between the True and False Percula Clown or Anemonefish is simply that the false species is tank-raised in captivity and has never seen the ocean. Hmmmm. So if this is the only reason these clownfish differ, and hypothetically you placed a "tank-raised" Percula into the ocean, does it miraculously become a True Percula Clownfish? What do you think?

To help with the identification of these two species, here are distinguishing differences that set them apart from one another, which is more than just being tank-raised or not.

In this photo, there are both True and False Perculas. Can you tell which is which?
