never bred oscars or kept them for long (too much appetite for me). That looks like breeding behavior to me. The small one exhibits a nice round female shape. Could be wrong. They look great and it doesn't seem they're harming each other. You should post this on the face off thread too.
 
doesnt look like any oscar fights ive had happen in my tanks. to me it seems more like a breeding thing than hostility. the damage on the smaller is only superficial and should heal quickly. my breeding pairs often engage in rough "foreplay" if you will before spawning.
 
yeah,I think that they have pair up and that's why they were so aggressive towards albino.
 
bump
any one?

unfortunately, very unadvisable. If you think Oscar's are greedy, get a load of these guys. They can easily get to 12 inches and are probably one of the greediest fish I have ever kept. I only had two and I got them at around 7 inches. They require a very large tank if you keep them in groups. They are extremely skittish fish so if not kept in large tanks, will for ever be swimming into things and get spooked quite easily.

I offloaded mine to a friend not long after I got them. I think they are around 10 inches now and she regretted taking them off me and is also looking for a new home for them.

As for whether or not your Oscars are pairing off ready to breed, I can't see any evidence of this by your video. Two Oscars will go through this behaviour and never breed. Try putting a large flat rock in your tank. Oscars nearly always choose surfaces like this to lay their eggs on. From the experience I've had a breeding pair of Oscars, a few days before they lay the eggs, they will concentrate on cleaning the surface where the eggs will be laid. They will become very territorial or not tolerate any other fish anywhere near the rock.

You may notice a swelling in the females abdomen when she has developed her eggs. You will also notice her breeding tube sticking out, you cannot miss it. And if they are about to breed, the males breeding organ will also be producing, this is much smaller, it looks like a little spike.

Occasionally, eggs will come from nowhere and completely surprise you. If the males organ is not protruding, then he is either not ready, possibly a female, or they are not paired up.

Very often, breeding is very erratic. It may be months in between eggs. Other times, eggs, are produced every few weeks.

That's my two for what it's worth
 
I only got my oscar 6 months ago and handfed him from day one.
He's got 6 silver dollars allways surounding him.
They entered the tank at allmost the same time and he's allways cool.
When disturbed they will all be hiding together, cuddling up to eachother!

I read once that a guy took his fishing net everytime one of his oscar behaved as an ***, and dipped it in the water.
It took him only a couple of days to train the fish not to harrass the other oscar.Don't know if its true, but I think it could work.
