Another question i have is that i have a huge and a somewhat small rock in the tank. The girl seems to hover over the larger one. This concernes me because the larger rock is not flat at all. its got humps and small slides. Then the male is hovering over the smaller rock that sits about two inches away from the larger one. I noticed a few dead fry behind the larger rock against the glass. Now what i want to do before she lays the eggs in vacume the dead and the fungus out so it is a cleaner area. Also remove the rocks that are in there now and replace with a flat rock that is better suited for her to lay her eggs. If i do this will it affect her egg laying? Will she still lay them?
I would get in then now and just clean your tank removing anything that will decay and cause water quality problems, don't worry about your fish, they will be okay, they will get on with things once you've finished. If an Oscar hasn't got a flat rock to lay on, they will find the next best thing, even sometimes clearing the substrates away and laying eggs on bare bottom of the tank.
