Need help ID those unicornfish

[Patrice]

Hi,

I am curious about unicornfish. They look all the same to me. I found some nice pics on fotolia but I am not sure which one is which one.

Do you have any idea what each are: Unicornfish #1, Unicornfish #2, Unicornfish #3

Ho and while I am here, do you know what surgeon fish this is: Unknown. I think this is a nice one but can't figure out who it is.

Thanks!
