Description: Dragon Fish
The Dragon Fish, also known as the Asian Arowana (Scleropages formosus), is a strikingly beautiful freshwater fish native to Southeast Asia. Renowned for its gleaming, metallic scales and elongated, dragon-like body, the Dragon Fish is a popular species among aquarium enthusiasts and is often associated with wealth and good luck in several Asian cultures. These fish can display an array of vibrant colors, including gold, red, and green. As a top predator in its natural habitat, the Dragon Fish is carnivorous and prefers a diet of live insects, smaller fish, or shrimp. Due to its protected status, ownership of Dragon Fish may require special permits in some countries. They require large tanks with pristine water quality and ample swimming space. The Dragon Fish can live up to 20 years or more with proper care, making it a long-term companion for dedicated aquarists.

Properties
The Dragon Fish, commonly referred to in the aquarium trade as the Asian Arowana (Scleropages formosus), is a freshwater fish that has achieved legendary status among aquarists and collectors throughout Asia.
The Dragon Fish is most well-known for its elongated, metallic body that can display a stunning variety of colors, ranging from gold and red to green and blue, depending on its specific variety and natural habitat. Its large, shiny scales are often likened to the mythical dragon, which is why this fish is regarded as a symbol of luck, prosperity, and strength in many Asian cultures. Its long pectoral fins and barbels (sensory whiskers) on the lower jaw further enhance its dragon-like appearance.
One of the key characteristics of the Dragon Fish is its unique swimming style. The fish usually glides gracefully near the water's surface, helped by its streamlined body and strong, undulating movement. This behavior is not only beautiful to watch but also rooted in its predatory nature, as it typically hunts for insects, smaller fish, and crustaceans from just below the water’s surface in the wild.
Dragon Fish are renowned for their intelligence and can be trained to take food from their owner’s hand. However, they are territorial and should generally be housed alone, as they can be aggressive toward other fish, particularly those of similar size or appearance.
With proper care, Dragon Fish can live for 15-25 years and reach sizes up to 35 inches (about 90 cm). They require large, well-maintained aquariums with excellent filtration, soft acidic water, and tight-fitting lids, as they are powerful jumpers. Due to their endangered status (classified as Endangered on the IUCN Red List), international trade is strictly regulated by CITES, and only captive-bred specimens should be kept.
In summary, the Dragon Fish is a striking and culturally significant species that combines beauty, intelligence, and a storied reputation, making it a prized possession for experienced fishkeepers willing to provide the specialized care these majestic creatures deserve.
Appearance
The "Dragon Fish," widely known as the Asian Arowana (Scleropages formosus), is a captivating freshwater fish species that boasts a remarkable and striking appearance. One of its most distinctive attributes is its elongated, streamlined body, which is covered in large, metallic scales. These scales shimmer in the light, creating an almost armor-like or iridescent effect, often compared to the mythical dragons from which the fish earns its common name. The scales are especially prominent, being thick and arranged in regular rows, giving the fish a distinct, textured look. Asian Arowanas come in various color morphs, most notably red, golden, green, and silver varieties, each with a slightly different hue and scale intensity, but all exhibiting a luminous, pearlescent shine.
The head of the Dragon Fish is pointed, with a pronounced lower jaw that slightly juts out, giving it a powerful, regal profile. Its mouth is upturned, designed for surface feeding, and beneath the mouth are two long, slender barbels. These barbels are sensory organs, reminiscent of the whiskers seen on traditional depictions of dragons, further contributing to the fish’s legendary name. The eyes are large and set towards the front of the face, providing a keen and alert expression.
The dorsal and anal fins of the Dragon Fish are long and extend far back along the body, meeting near the tail and giving the fish an almost ribbon-like silhouette when viewed from the side. The caudal (tail) fin is fan-shaped and robust, while the pectoral and pelvic fins are relatively small in comparison. The fins, especially in more mature specimens, can sport faint touches of coloration that often match the body or appear slightly more translucent.
The overall posture and swimming style of the Asian Arowana are graceful and commanding. When moving through the water, its undulating motion and vivid reflections evoke imagery of a mythical dragon gliding through the clouds. The Dragon Fish can grow to substantial sizes, sometimes exceeding 90 centimeters (about 35 inches) in captivity, and exhibits a physically imposing presence. Because of its unique blend of elegant proportions, shimmering metallic color, and dragonlike features, the Dragon Fish has become one of the most coveted and admired ornamental fish species in aquaculture, often signifying prestige and good fortune in various Asian cultures.
History
The Dragon Fish, also known as the Asian Arowana (Scleropages formosus), is a freshwater fish native to Southeast Asia and is renowned not only for its striking appearance but also for its rich and storied history. Historically, the Dragon Fish has been found in slow-moving rivers, swampy areas, and flooded forests of countries such as Indonesia, Malaysia, Thailand, Cambodia, and Vietnam.
References to the Asian Arowana in cultural lore date back hundreds of years, especially in Chinese legend and feng shui practices. The fish is often called 'Dragon Fish' because of its resemblance to the mythical Chinese dragon; its elongated body, shiny metallic-like scales, and barbels (whisker-like appendages) jutting from the tip of its lower jaw contribute to this likeness. In Chinese culture, the dragon is a symbol of power, wealth, and prosperity, and so the Dragon Fish has been venerated as a bringer of good luck and fortune. It is commonly believed that the fish can ward off evil spirits and misfortune, making it a sought-after pet among the affluent and business-minded.
In the 20th century, overfishing, habitat loss, and the exotic pet trade combined to make wild populations of Dragon Fish increasingly rare. In fact, by the 1970s, the species was designated as Endangered by the International Union for Conservation of Nature (IUCN) and was listed under Appendix I of CITES (the Convention on International Trade in Endangered Species), severely restricting international trade. As a result, most legal Dragon Fish available today have been bred in captivity, with each fish typically microchipped to ensure traceability and legality.
The development of color varieties—such as green, red, gold, and silver—has further heightened the fish's allure and led to significant advances in aquaculture, particularly in Malaysia and Indonesia. Today, breeding farms employ sophisticated techniques to enhance coloration and ensure genetic diversity. The history of the Dragon Fish reflects not only its biological and ecological significance but also its enduring cultural impact as one of the most mythologized and sought-after ornamental fish in the world.
