If your tank is 300gals +, maybe.
The argentea would at first be at a disadvantage if the others have been there a while and set up territories. But argentea an get very domineering after they reach about 7 inches, and they don't like other laterally compressed fish with color similar to theirs.
I also believe the oscars and chocolate are not even close to being tough enough to be with argentea.
I had an alpha male constantly pin a large dovii in one corner, and a managuense in another corner of a 150 gal tank (tank was just too small). I had to give the argentea its own tank to save the lives of the others.
