Currently have a 225 gallon tank. It’s 6’L,20”w,3’T.
It’s currently being occupied by a 9” copper red Oscar, 10-11” albino chili Oscar, 20” ornate bichir, and a 22” clown knife. Currently trying to rehome the clown knife.

My problem and question is the clown knife stresses out the Oscar’s a ton. I have 4 more albino tiger Oscar’s 10”+.

Should I add the other 4 Oscar’s to reduce aggression? Filtration is not an issue. I can add more as necessary.

Attached is the current tank
