That means you probably only have a tank capable of holding ONE JUVENILE Oscar and nothing more. As an adult single Oscar, or with any other fish, you would need a bigger tank.
If you do get a bigger tank, compatible fish in my experience are: Silver Dollars (by far the best tankmate I have found for mine), Plecos (if larger than the Oscar by a long way) and fully grown Convict Cichlids (just one).
