Thanks for reaching out. Arowanas and oscars are both fairly aggressive fish, so placing them all together might end up in aggression. Arowanas also grow a lot larger, so over time, aggression might develop. Providing plenty of hiding spots and keeping them well fed might diminish aggression and territoriality. For more additional information about arowanas, contacting a local fish group might provide more information. Telling everything about arowanas is a pretty large request. Good luck.
