The Chinese dragon fish is not a real species; it is a popular name for the Asian arowana (Scleropages formosus), a freshwater fish revered in Chinese culture as a symbol of wealth, prosperity, and good fortune. Its name comes from its long, sleek body, large metallic scales, and whisker-like barbels, which together evoke the appearance of the mythical Chinese dragon.
What Is the Chinese Dragon Fish?
In the aquarium trade, “Chinese dragon fish” almost always refers to the Asian arowana, also known as the dragon fish or golden arowana. Native to Southeast Asia—particularly Malaysia, Indonesia, and Thailand—this fish is not actually from China, but it has deep cultural ties to Chinese communities worldwide. The fish’s resemblance to the dragon, a central figure in Chinese mythology, has made it a highly prized and expensive aquarium specimen.
There are several color varieties, including the red, gold, green, and silver arowanas. The most coveted is the Malaysian golden arowana, which has a bright gold sheen and is often called the “golden dragon fish.” These fish can grow up to 90 centimeters (about 3 feet) in length and live for decades, with some reports of individuals exceeding 50 years in captivity.
Why Is It Called a Dragon Fish?
The name comes from the fish’s physical features. Its long, streamlined body, large scales, and two barbels near its mouth resemble the whiskers of the Chinese dragon. In Chinese culture, the dragon symbolizes power, strength, and good luck, and the arowana is often called the “dragon fish” because it is believed to bring similar blessings to its owner.
In feng shui, the arowana is considered a powerful symbol of prosperity and success. Many owners place the aquarium in a specific part of their home or office to attract positive energy. The fish’s ability to jump out of the water to catch insects also adds to its dragon-like mystique, as dragons are associated with the sky and water.
History and Cultural Significance
The Asian arowana has been kept as an ornamental fish for centuries, but its popularity surged in the late 20th century, particularly in Hong Kong, Singapore, and other Chinese-majority regions. The fish is often given as a gift during business openings or as a symbol of status among wealthy collectors.
In Chinese mythology, the dragon is a benevolent creature that controls water and brings rain. The arowana’s habit of leaping from the water is seen as a sign of ambition and success. Some owners even believe that the fish can sense danger or bring luck to their families, though these beliefs are cultural and not scientifically supported.
How to Choose a Chinese Dragon Fish
Selecting an arowana is a serious decision due to its cost and care requirements. Here are key factors to consider:
- Color and quality: Look for vibrant, uniform scales and a clean, unblemished body. Red and gold varieties are more expensive than green or silver ones.
- Age and size: Younger fish are cheaper but require more care. Adults are larger and may be easier to keep, but they need a very large tank.
- Health: Check for clear eyes, intact fins, and active swimming. Avoid fish with cloudy eyes, frayed fins, or visible parasites.
- Legal status: Asian arowanas are listed under CITES (Convention on International Trade in Endangered Species). Ensure the fish has proper documentation and is legally sold in your country.
Common Problems and Misconceptions
One major misconception is that the Chinese dragon fish is a type of carp or koi. In reality, it is an arowana, which belongs to the ancient family Osteoglossidae. Another myth is that all arowanas are illegal to keep; in fact, only wild-caught Asian arowanas are heavily restricted, while captive-bred specimens with CITES certificates are legal in many places.
Common health issues include:
- Dropsy: A bacterial infection that causes the scales to protrude; often fatal if untreated.
- Fin rot: Caused by poor water quality; treatable with water changes and medication.
- Jumping: Arowanas are notorious jumpers; a tight-fitting lid is essential to prevent injury or death.
Cost and Investment
The price of a Chinese dragon fish varies widely. Juvenile silver arowanas may cost around $50, while adult Malaysian golden arowanas can fetch thousands of dollars. Rare albino or platinum varieties have sold for over $100,000 in extreme cases. The cost also includes a large aquarium (at least 250 gallons for an adult), high-quality filtration, and a diet of live or frozen foods. Owners should budget for ongoing expenses such as electricity, water treatments, and veterinary care.
Conservation and Legal Status
The Asian arowana is listed as endangered in the wild due to habitat loss and overcollection. All species of Scleropages formosus are protected under CITES Appendix I, which prohibits international trade of wild-caught fish. However, captive-bred arowanas from licensed farms can be legally traded with proper permits. Many countries, including the United States, allow ownership of these farm-bred fish, but it is crucial to verify local laws before purchasing.
Frequently Asked Questions
Is the Chinese dragon fish a real dragon?
No, it is a fish—specifically the Asian arowana. The “dragon” in its name is a cultural reference to the Chinese dragon, not a literal creature.
Can I keep a Chinese dragon fish in a small tank?
No. Arowanas grow to be 2-3 feet long and need a minimum tank size of 250 gallons for an adult. A small tank will stunt their growth and cause health problems.
What do Chinese dragon fish eat?
They are carnivorous and eat insects, small fish, frogs, and crustaceans. In captivity, they can be fed pellets, frozen foods, and live prey, but a varied diet is essential.
Are Chinese dragon fish illegal to own?
Not necessarily. Wild-caught Asian arowanas are illegal to trade internationally, but captive-bred fish from licensed farms are legal in many countries if you have the proper CITES documentation. Always check your local laws.
How long does a Chinese dragon fish live?
With proper care, they can live 20 to 50 years, with some reports of individuals living even longer. They are a long-term commitment.
Do Chinese dragon fish bring good luck?
In Chinese culture, they are believed to bring prosperity and success, but this is a cultural belief, not a scientific fact. Many owners keep them for their beauty and symbolism.
