Well, I thought the same thing too...but compared to the other regular ocellaris clowns in the LFS, this guy looked considerably darker.
Mind you though, he's not as dark as some other Mocha's that I've seen.
In person, his head, belly, and fins are orange w/no black. And his upper portion of the body looks black with an orange tinge.
He's (from what I was told) a mix of a reg ocellaris and a black and white ocellaris. From what I understand, they get darker in color as they get older. I guess I'll find out when I try to pair him with a black and white
lol The LFS guy said since he's a mix, he can be kept with either of those.
