The eyes are the quickest and likely the most reliable method for telling an A. percula from a A. ocellaris. The spines are not reliable at all, do to the overlap and common malformation/development, especially in small/yound fish.
But the eyes, should NOT be the sole reason to make an ID. The overall look of the fish, the coloration, body posture, fin shapes, etc, etc should all suuport the quick ID based on the eyes.
