Black and White Clownfish confusion!

[kdblove_99]

Ok,

I'm confused, What's the difference between Black Perculas and black Occelaris? I see pics and they look the same to me.

Also I see some that have orange on the face, I believe i have read those are juveniles? Will they eventually turn completely black or will the orange stay?

Like this one from Liveaquaria says its an adult but still has some orange. I want one that is completely black

I also see some ORA farm raised or usally Australian tank raised much diffrence in the fish?
