Asian Arowana is an Endangered Species
The Asian Arowana is an endangered species that is protected by the Endangered Species Act. The fish was banned from international trade in 1975.

However, because it is a valuable luxury commodity, the Asian Arowana trade is a thriving business in the black market world.
Often, the trade is associated with some of the most heinous crimes, including murders in the leading cities of the world.
Asian Arowana Natural Habitat
The Asian Arowana lives in black water rivers found in the regions of South East Asia. They inhibit slow-moving waters that flow through the swamp.
They also live in other wetlands. Adult Arowana hunts other fish and big prey for food. On the other hand, the young fish feed on smaller insects, which are plenty in the swampy waters.
All the other different species of Arowana can do well in freshwater environments. They can also survive in environments with less oxygen as compared to other common fish species.
A low oxygen environment helps the Arowana to wade off any stiff competition for food from the other fish species. Besides, the prey that inhabits lower oxygen environments tends to be weaker and thus are easy targets for the hungry Arowana.
Other places where you can find Arowana include flooded forests, river basins, ponds, freshwater lakes and rivers.
The Asian Arowana spends the day brooding and hiding in the roots of aquatic plants or other water structures. Typically, they only come out at night to feed and play.

You can raise the juvenile fish in smaller tanks of about 60 gallons. However, you will need to move them into larger tanks as they grow. Failure to move them into larger tanks results in body deformation, and premature deaths.
You can decorate the tank using sturdy plants, rockwork, or driftwood. Ensure you don’t use plants with weak roots that can be easily dislodged by aggressive fish.
Whatever variety you choose to keep, you need to consider that arowanas are strong, powerful swimmers and aggressive fish too. Therefore the tank should be spacious enough to allow for some acrobatic practice and crazy speed swimming.
Ensure the tank you choose is sturdy, durable, and reliable. Arowanas can grow up to 4-foot (120 cm) size to weight over 13 pounds (6 kg). You should also expect your Arowana to live for up to 15 years with appropriate care.

In their natural habitats, arowanas lay eggs at the onset of the flood season, usually in the months of December and January. The couple first builds a nest from where the female fish lays eggs. The Arowana eggs are either orange or red.
