Actually, here is your definitive way to tell them apart. They are either
Amhiprion percula or
Amphiprion ocellaris. I bet juvenile
A. ocellaris in all the pictures. As they get older, their orange face will fade and they will be all black.
A. percula: Dorsal spines (total): 9 - 10; Dorsal soft rays (total): 14 - 17; Anal spines: 2; Anal soft rays: 11 ââ"šÂ¬Ã¢â‚¬Å“ 13

A. ocellaris: Dorsal spines (total): 10 - 11; Dorsal soft rays (total): 13 - 17; Anal spines: 2; Anal soft rays: 11 ââ"šÂ¬Ã¢â‚¬Å“ 13

Here are some pictures with their common names with them.
A. ocellaris black var.: Black and White Clownfish, Black and White Ocellaris
A. percula black var.: Onyx Percula, Onyx Clownfish, Black and White Percula, Black and White Clownfish.
Also, when shopping for a Black and White Percula or Ocellaris, make sure that you aren't buying an A. polymnus black variant.
