Oscars prefer to lay their eggs on a flat surface, they will not lay their eggs directly on the substrate. If there is nothing in the tank for them to lay their eggs on, they will clear a patch of gravel/sand until the bottom of the tank is exposed and then they will lay their eggs there. If you want your Oscars to breed then you are probably wise to put something in the tank like a piece of flat slate or rock.
Oscars will often choose a location for where they are going to start laying eggs a long time before they actually start breeding properly. I also believe that Oscars go through a kind of dress rehearsal before they actually start laying eggs. The reason I say this as I have observed my Oscars going through a similar procedure in exactly the same way they would if they were actually laying eggs. Fish wIll survey an area before deciding whether or not it is suitable. After all, breeding is probably the most important thing that goes on in nature and animals will go to great extents to make sure their offspring survive.
