My cousin had an oscar once, three actually. He had a huge tank setup, which is recommended since oscars are bigger fish. I believe his was a 50 gallon, if I am not mistaken.
Anyway they were beautiful fish, and were fairly active in the tank. His tank had all kinds of plants in it. I remember the first time I seen him feed them pieces of worms... I was thinking damn they are fairly big for a home setup. (My fish are just little things that eat flake food and occasionally shrimp)
This experience of watching the oscars eat the worms made me realize they would not get along with other fish, and soon become food if introduced with other fish. My cousin mentioned getting other types of fish, and I strongly encouraged him not to.
Besides one of the oscars was acting aggressive towards the other fish at feeding time if they came to close to were he was feeding at.
So in closing, I think they are beautiful fish, but have a tendency to be misbehaved. They also require a big setup, so your 10 gallon tank will most likely not make your oscar happy, and you definitely want to keep them happy! Also, while they can be housed with other oscars, I think one oscar may be plenty for your tank.
In the end the choice is yours, but I think I will stick to my glo fish and guppies!
