I think captive bred percs may lose their black banding, and forget trying to count dorsal spines unless you like a whole lotta frustration. "Hold still I say!" What's worse, even if you did count them, dollars to donuts you'll count 10. And technically percs can have 9 or 10, and ocellaris can have 10 or 11. Whee! Guess how many MY percularis fish have??
I couldn't see the pictures you posted because of some firewall issue (Stupid McAfee).
Anyhow, one method that clownfish guys swear by, is the colour of the ring around the eye. If it's clear (or orange), it's
A. ocellaris. And if it's dark, muddy, or outright back then it's
A. percula.
HTH
