Can I keep Arowana with other fish?

Arowana are also highly territorial but establish good relationships with other fish such as Barbs, Parrot Fish and Stingrays. If you desire to keep a number then as a general rule they can only be kept with other Arowana if in groups of 6 or above. As a testament to their individual personalities it is often possible to keep smaller groups of Arowana together if they are individually more sociable.
Always keep watch over your tank and fish to understand the relationship that are forming. Also remember the Arowana’s primary territory is within 16 inches of the surface of the water. If you have fish that regularly swim in this zone they are prime targets for Arowana to pick on. If your tank is not deeper than 16 inches you may find keeping any other fish will be a problem.
