Can anyone tell me if this behavior is friendly or aggressive?
I put two same size, juvenile Oscars in a new 75 gallon tank together at the same time. They basically shadow each other all over the tank, even in direct contact with each other. My girlfriend said, "they're married," but I have my doubts. I thought maybe the shadowing was some sort of dominance display, like, "hey, if you're going over there then so am I, cause this is my tank!" Though they switch the role of which one is following and which one is followed. Occasionally one will try to get under the other but it doesn't seem to bother anyone. So far I haven't seen any biting or nipping.
I've never put two Oscars together so I have no idea if this is good or bad.

Its a normal oscar thing...my parents have 2 oscars in the tank in the living room...they do the same behavior. I wouldnt worry until you get open mouthed gill flaring full on displays. Then youll know either you have territory battles or a potential pair.
