Two clowns, different colors... Same type?

[adee]

So, I have had my clown a year or so and it's pretty big and very vibrant, my sister was breaking down my nieces tank and decided to gift us her clown and a few damsels (damsels went into the empty sw tank in my kids room, it's been running with just cuc, water and rock for a few weeks) I was curious though, her clown is tiny and much lighter in color... Is it because of diet or is it an entirely different type of clown?

Ocellaris and Percula clowns look very similar. They easiest (not 100 % accurate) way to tell the difference is to look at their eyes. Percula's have more yellow around their eye and Ocellaris have solid black eyes. The most accurate way (also the hardest) is to count the rays on their dorsal fin, 10 for a Perc 11 for an Oc.

Going by eyes looks like I have one of each? Percula being the brighter, bigger one we've had forever
