Your tanks go agains what you are saying in all of your posts.
the poster specifically wanted Oscar’s. Not the cichlids you recommended. And none of the fish you recommended (sans maybe green Terrors) would live well with an Oscar.
and I addressed a fish that was a genetic anomaly size wise (he has a few inches on brick) that is happy and healthy in a tank smaller than what you are saying. and yes I would recommend 4 Oscar’s for an 8 foot tank to my clients, customers, and friends. And with proper care I believe they would be happier and healthier than the stocking arrangements you recommend and utilize.
arguing does not help the original poster. So I will make it very simple.

you can have four Oscar’s if your tank is 8 feet or two meters long. Just feed and water change properly
