A 6ftx3ft(width)x2ft is going to be small for a Silver Aro and an Oscar?
(I have already placed the order for this tank. I don't plan on getting anything bigger given the size of my apartment in Bombay.)
I think if there is no problem "temperament" wise (ie no fights), I will keep both of them for a couple of years and then sell/give away the Oscar when the tank seems too small for them.
My immediate concern was the Oscar troubling the Silver Aro.. That's not going to be a problem, right?
