Hate to be the bearer of (possibly) bad news, but that is an Amphiprion Ocellaris (Ocellaris Clownfish), not Amphiprion Percula (True Percula Clownfish). And definitely not a Purculla..
Usually a substantial difference is price between Ocellaris and Percula, Percula being the more expensive one. Hopefully your LFS didn't sell you a Ocellaris at Percula Prices.
Nice looking Clown though.
