Oscar Beeding?

So I have 3 Oscars 2 of the standard, and 1 albino. My question is as of the last week the albino and one of the standard have each chosen a flat stone on opposite ends of the tank. They have cleared them off and just hover above them only leaving them to feed. Do I have breeding Oscars or will all male or all female still display this behavior? They are also attacking the 3rd oscar or pleco if they get too close. I recognize this as breeding behavior but unsure if I should expect fry or what. Thoughts?
