The Arowana originated from the Amazon River basin. Variations on the
spelling of the name include Arrowana, Arawana, and Aruana. It is also
called the Dragon Fish and the God Fish. The Silver Arowana has large
silver scales. The dorsal and anal fins are set far back and almost merge
into the tail fin. Another distinctive feature is the presence of a tongue
that protrudes from its mouth.
The Arowana is not a beginner fish, because it
needs very clean, clear water and lots of space - at least 55 gallons and
preferably 300. Arowanas are very tolerant of variations in pH and water
hardness. They can breathe air for short periods of time.
Arowanas are very popular for the beauty of their swimming patterns.
Feeding an adult Arowana is expensive. They can be fed live and frozen
brine shrimp, live black worms, live crickets, floating pellets, arowana sticks
and any live fish that will fit in their mouth. They will also eat meat,
but if they have been raised on feeder guppies or goldfish, they will not take
to meat easily. They only take food from the surface. In the wild,
they will leap from the water to catch insects. They are also easily
scared. A covered tank is essential and the lid should be weighted down,
as they can force their way through most aquarium lids. As they mature,
they become aggressive toward their own kind.
It is nearly impossible to distinguish the sex of a Silver Arowana. To
establish mating pairs, raise a young group and allow them to pair
naturally. They reach sexual maturity at 3 years of age. Breeding is
not difficult once you have a large enough tank. The pair will swim in
circles and the female will lay 50 - 250 eggs for the male to fertilize.
Arowanas are mouth brooders. The fry will stay in the male’s mouth for
over a month before they are free swimming.

The most important criteria for tank mates is size,
as Arowana will eat any fish that fits in its mouth.
