My Oscars are 11" and are only 14 months old. If they are a year the should be at least 10 inches. Oscar grow fast if given the space and proper care.
Oscars and Live Plants: Oscars like most cichlids dig. They often dig up and through this process destroy plants yes, but it also depends on the personality of the Oscar. I have live plants only one have died. It was "in the way" of the Oscars as they dug out a piece of slate for breeding.
Oscars have been known to destroy heaters and decorations. The also move decor and set the tank the way they want it to look.
