Whats wrong with my fish ??

[janalta]

Looks like she's developing white spots...not good.
Can't tell for sure if it's ich or Velvet.....do you have a knowledgable LFS nearby you can take her to ?
Treating for parasites in your tank could mean death to all inverts and corals...but you may not have any choice at this point.
It also means not adding any more livestock for approx 6 months after all signs of it are gone.
