Rob,
That is not what criccio is saying.
A. clarkii is the latin name of a specific clownfish species. It is the most widely dispersed clown in the wild and is available in the most color varieties, easily greater than 30.
If you follow the link criccio provided, you will see many many of the varieties of A. clarkii.
A. bicintus, A. akindynos, A. chrysopterus, A. allardi, A. chrysogaster, etc., etc., are within the Clarkii Complex, but are separate and distinct species.
Some of the of the folks that have answered your question and ID'd your fish have been working with clowns for many many years. It is up to you to either accept or disregard their opinions, but I don't think you'll find too many folks in disagreement on the ID.
fwiw: It is a nice looking specimen, many get real ugly at maturity. Congratulations on taking great care of it.
Cheers.
