That would depend on the size of your tank and the size of the oscars. Arowanas need a lot of space usually. I have seen them successfully being kept with arowanas before, but the oscars must be at least the same size of their mouth, not smaller. Unfortunately there are not fixed ruled and the only way would be to try them out together. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
