back together like just 2weeks? the other one shakes its tail and when they were fighting they were dancing around circles what does that mean.and also their only young oscar fish do i separate them?or put them together?any suggestion? Ladies and gentlemen.
 
They are vying for territory. They are fighting to see who the dominant fish is . They are very aggressive fish.Separate tanks is the answer.
 
Some of the answers about larger tanks have some merit. Your young Oscars should have a fairly large tank,I'd say around 70 gallons as a minimum.
However what you describe as fighting is common cichlid behavior and should not be a problem at all. If your fish are "lip-locking" (grabbing one another's jaws and shaking), or threatening behavior (lateral displays) don't worry. I wouldn't consider separating them unless they were actually loosing scales, and even then if there were no serious injuries I'd let nature take it's course.
Perhaps you should do a little more research into Oscar behavior, it's most interesting.
 
Oscars are very aggressive fish. Is your tank 110 gallons? If it isn't then that is your problem. 1 Oscar should have a minimum of 55 gallons, more than 1 needs 110 gallons. These fish grow very big and may end up killing each other.
