Overview
The Asian Arowana is one of the most famous fish in the world, sometimes called the 'dragon fish' because its large shiny scales and long body look like a Chinese dragon. It lives in the slow, dark rivers and flooded forests of Southeast Asia, where it cruises just under the surface waiting for food to come near. In some cultures it is believed to bring good luck, which has made it very valuable.
Because wild Asian Arowanas became rare, they are now a protected species and international rules control who can own or sell them. They also grow around three feet long, far too big for a normal home aquarium. For all these reasons this is a fish to admire in photos, public aquariums, and licensed collections rather than a pet to keep at home.

Where it lives
Asian Arowanas live in the warm, slow-moving rivers, swamps, and flooded forests of countries like Malaysia, Indonesia, and Thailand. The water is often dark and stained brown from fallen leaves. The fish spends most of its time near the surface, gliding slowly with its long body and using two little whiskers on its chin to sense movement in the water.
Amazing hunter
This fish is a powerful surface hunter. It has a big upward-facing mouth and can leap right out of the water to grab insects, spiders, or even small lizards resting on low branches. Because of this jumping habit, it earned the nickname 'water monkey' in some places. Its excellent eyesight helps it spot prey both under and above the water.
A caring parent
Asian Arowanas are mouthbrooders, which means a parent carries the eggs and babies inside its mouth to keep them safe. The father holds dozens of large eggs in his mouth for weeks, not eating much, until the young are big enough to swim on their own. This careful parenting helps more babies survive in the wild.
Why it is protected
Because people prized the Asian Arowana for luck and beauty, too many were taken from the wild and its rivers were damaged. Today it is listed as an endangered species and is protected by international law. The ones sold legally are raised on special licensed farms and carry a microchip and certificate to prove they were bred, not caught in the wild.

Frequently asked questions
Can I keep an Asian Arowana at home?
In most places no. It is a protected, restricted species and it grows about three feet long, which is far too big for a normal aquarium. It belongs in public aquariums or specially licensed collections.
Why is it called the dragon fish?
Its long body and large, shiny, overlapping scales look like the dragons in Asian art and stories, so people gave it that nickname.
How big does it get?
An adult can reach around 35 inches, which is almost three feet long. That is bigger than many house cats are long.
Is it really endangered?
Yes. Wild populations dropped because of collecting and habitat loss, so it is now protected by international law and only farm-raised, certified fish can be sold legally.
