Before I purchase this Clownfish (what is this)

[\Clownfish/]

There is a small white type of film on her tail but only a small spot. I saw it at my LFS and she is the only one In the tank. I was debating on purchasing her but wanted to know what it is before I do.

Could be brook, or velvet. Can't tell from photo. Do not buy a blemished fish. Give the store a miss for a prolonged while, since the stuff can travel through the shared water system.

I think you maybe right sk8r. It's on her tail and it looks filmy. Best shot I could get.

It looks kind of like Lymphocystis IMO. Being that Ocellaris clownfish are extremely common though I would definitely hold out for another one.
