Some fish that might live in an aquarium with arowana are clown knifefish, pacu,oscars, plecostomus, jaguar cichlids, green terrors, gar and any other semi-aggressive fish that are too big to be eaten. Australian arowanas are best kept alone.
I have heard of a Discus Breeder who tried to keep Adult Discus and Arowana in the same tank since they need similar water parameters. He failed. I would not advise anyone to keep anything with Arowanas. They are ferocious predators, and get far too big. (Around 13 to 14 feet long in captivity). You would need a very large aquarium to keep one alive for any length of time.
Feeding an arowana depends upon it's size, if the fish is 3-5inches try feeding it with small live feeding fishes ensure good health of the live feed. Then start with recommended arowana pellets if asian arowana. After the fish gains a good size feed it with shrimps, live feed, Arowana pellets as how does the fish gets used to the above feeds. its better to avoid the live fish feed for a longer time as it may cause infection to your arowana & majorly the arowana may suffer from dropeyes(refer internet for the precautions). Temperature plays a vital role in good arowana keeping. Ensure a huge tank size for keeping it with a good aquarium top as these fishes are high jumpers & require a good size aquarium ( min 4ft- 8ft avrg size).
