Distinguishing Features

  • Elongate body with large metallic-looking scales; upturned mouth adapted for surface feeding
  • Two prominent chin barbels typical of arowanas
  • ‘Platinum’ individuals show very pale/whitish coloration due to reduced pigmentation (a morph/variant rather than a taxonomic distinction)

Secondary Colors
Skin Type Large, thick cycloid scales; smooth, armor-like and highly reflective; surface-dwelling posture accentuates dorsal shine.
Distinctive Features
  • Adult size: up to 90 cm total length (FishBase: Scleropages formosus).
  • Longevity: commonly 20+ years in captivity; long-lived for large teleosts (aquarium husbandry reports; varies by care).
  • Two chin barbels on lower jaw; tactile/chemosensory aid during surface feeding.
  • Upturned mouth and superior jaw; surface-feeding predator that strikes insects and small fishes.
  • Long dorsal and anal fins set far back, giving an undulating, gliding swimming profile near surface.
  • Large reflective scales arranged in regular rows; in platinum morph, scale "rim" can appear pearly.
  • Known to jump powerfully when startled; tight lids recommended (documented aquarium behavior).
  • Trade/regulation context: wild populations protected; international trade controlled under CITES (listed; permits/registered breeding required).

Sexual Dimorphism

Sexual dimorphism is subtle. Males often show a slightly broader head/lower jaw and longer dorsal/anal fins, especially in breeding condition; females tend to be deeper-bodied when gravid. Field sexing remains unreliable without breeding cues.

  • Slightly broader head and lower jaw in many adults
  • Dorsal/anal fins may appear marginally longer and more pointed
  • Often the paternal mouthbrooder in this species (reproductive behavior)
  • Deeper, rounder abdomen when carrying eggs
  • Body may appear slightly fuller through midsection
  • Typically lacks the more pronounced head/jaw proportions seen in some males

Did You Know?

Reaches up to 90 cm total length (FishBase) and is built for cruising just under the surface.

"Platinum arowana" is a trade name for an unusually pale/white (often leucistic) morph of Scleropages formosus-not a distinct taxon.

Has two chin barbels used as tactile/chemosensory "feelers" while hunting at the surface and around structure.

Arowanas are famous jumpers; aquarists use tight lids because they can launch upward to seize prey above the waterline (behavior widely documented in osteoglossids).

The Asian arowana is listed as Endangered (IUCN) and is regulated under CITES Appendix I; legal trade typically involves registered captive-bred fish with individual ID (commonly microchips).

Parental care is advanced: males mouthbrood-carrying eggs/young in the mouth until they are well developed (a hallmark of the genus Scleropages).

Wild populations occur in slow, often tannin-stained waters (including peat swamp/blackwater habitats) across parts of Southeast Asia, making habitat loss a major threat (IUCN).

Unique Adaptations

  • Chin barbels: paired sensory appendages under the lower jaw that help locate prey and navigate near-surface microhabitats.
  • Upturned mouth and surface-oriented head shape: optimized for capturing prey from below at the air-water interface.
  • Osteoglossid "bony tongue" apparatus: specialized oral anatomy (family trait) that helps grip and manipulate prey.
  • Large, armor-like scales: thick scales with reflective sheen; in platinum/leucistic morphs, reduced dark pigment can make the metallic base appear white-silver.
  • Air-breathing assistance: like many large tropical fishes, can tolerate low dissolved oxygen by using the swim bladder as an auxiliary respiratory surface (reported for arowanas/osteoglossids in low-O₂ waters).

Interesting Behaviors

  • Surface-feeding posture: patrols just under the surface, orienting upward to pick off insects, small fish, and other prey items.
  • Jump-strike hunting: can accelerate vertically to snatch prey at/above the surface-one reason secure aquarium covers are standard husbandry.
  • Territorial cruising: individuals often maintain and patrol a preferred zone, especially in confined spaces, showing aggression toward similar-shaped fish.
  • Paternal mouthbrooding: the male holds eggs/larvae in the buccal cavity, reducing feeding while guarding the brood.
  • Low-light activity: in naturally tea-colored/blackwater habitats, relies on silhouette tracking and surface cues; in aquaria often becomes most active at dawn/dusk lighting transitions.

Cultural Significance

The Asian arowana (Scleropages formosus) is a “dragon fish” of luck, protection, and status in China and Southeast Asia. High value drove demand; it is Endangered and on CITES Appendix I, with trade mostly limited to registered, captive-bred fish with microchips and papers. The platinum morph is highly prized.

Myths & Legends

Dragon-fish guardian (Chinese diaspora traditional geomancy): Arowanas kept in homes or businesses are often treated as living dragon analogues believed to draw wealth and deflect misfortune, with special "lucky" attention given to rare color types.

East Asian tale: a carp that leaps the Dragon Gate becomes a dragon. Now it's told about dragon fish like the Asian arowana (Scleropages formosus), kept for luck in rank, exams, business.

Some keepers say a prized Asian arowana (platinum color morph, Scleropages formosus) may take on illness or bad luck meant for the household, so it is seen as a spiritual protector.

During the 20th-century aquarium boom, the Asian arowana (platinum color morph) (Scleropages formosus) became a luxury "royal" dragon fish, thought to bring power and luck, creating a lasting cultural mystery amid modern conservation rules.

Conservation Status

EN Endangered

Facing a very high risk of extinction in the wild.

Population Decreasing

Protected Under

  • CITES Appendix I (international commercial trade in wild specimens prohibited; regulated trade largely via registered captive-breeding/ranching and marking systems).
  • National protections exist in several range states (species-level protection and harvest/trade controls; enforcement varies by jurisdiction).
  • Scientific reference: IUCN Red List-Scleropages formosus assessed as Endangered (EN) with a decreasing trend (latest available IUCN assessment).
  • Scientific reference (size/longevity): FishBase reports maximum total length ~90 cm and longevity to ~20 years for Scleropages formosus (values vary among sources and populations).
  • HUBS (Osteoglossidae/related arowanas): conservation statuses range from Least Concern to Endangered; common threats are habitat loss in lowland rivers/peat swamps and intense aquarium/food trade. Notable high-risk taxa include the Asian arowana (S. formosus) and other range-restricted arowanas with heavy trade pressure.

Reproduction

Mating System Monogamy
Social Structure Socially Monogamous
Breeding Pattern Seasonal
Fertilization Substrate Spawning
Birth Type Substrate_spawning

Asian arowana typically forms a temporary breeding pair; the female releases roughly 30-100 large eggs, the male fertilizes them externally and then immediately mouthbroods the eggs and fry for about 6-8 weeks until juveniles disperse.

Behavior & Ecology

Social Individual Group: 1
Activity Crepuscular, Diurnal
Diet Carnivore Small fishes and surface-fallen insects (opportunistic; no single universally documented 'favorite' prey item in wild populations).

Temperament

Strongly territorial toward conspecifics; aggression increases in confined spaces (aquaria).
Predatory surface-oriented ambush hunter; will ingest smaller fishes/invertebrates opportunistically.
Breeding males reduce feeding during mouthbrooding; paternal care is prolonged for a teleost.
Platinum (leucistic) color morph is a pigmentation variant; no robust evidence of consistent behavioral differences versus wild-type.

Communication

Visual signaling: lateral display, fin erection, head-up posture at surface during territorial encounters.
Mechanosensory cues via lateral line to detect surface vibrations/prey strikes in low-visibility water.
Chemical cues (waterborne signals) likely involved in reproductive state recognition, as in many freshwater teleosts.
Tactile contact and close following during courtship/spawning; male collects eggs for mouthbrooding.

Habitat

Biomes:
Tropical Rainforest Freshwater Wetland
Terrain:
Riverine Plains Muddy Valley
Elevation: Up to 656 ft 2 in

Ecological Role

Upper-level mesopredator in Southeast Asian blackwater/forest-river systems; links riparian (terrestrial) and aquatic food webs via heavy use of surface-derived prey.

Regulates populations of small fishes and aquatic invertebrates near the surface and in littoral habitats Transfers energy/nutrients from terrestrial insects falling into water to aquatic predator biomass (cross-ecosystem subsidy pathway) Acts as prey (especially juveniles) for larger piscivores/reptiles, contributing to trophic structure and energy flow

Main Prey:
Small teleost fishes Aquatic insects and other arthropods Terrestrial insects Freshwater crustaceans Invertebrates Small amphibians

Human Interaction

Domestication Status

Semi domesticated

Asian arowana (Scleropages formosus) is not domesticated but is widely captive-bred and bred for ornamental traits, including very pale "platinum" morphs. Wild stocks are threatened; the species is on CITES Appendix I. Registered captive-breeding with paperwork and microchipping supplies aquariums, especially from Singapore, Malaysia, and Indonesia.

Danger Level

Low
  • Bite/laceration risk when handling large individuals (strong jaws; can strike at the surface during feeding).
  • Injury/property damage risk from powerful jumping (arowanas are notable jumpers; unsecured lids can lead to fish escaping and people being struck or cut by glass/fixtures).
  • Routine aquarium zoonosis risk (e.g., non-tuberculous Mycobacterium exposure from aquarium water) if cuts are exposed-standard aquarium hygiene mitigates this.

As a Pet

Suitable as Pet

Legality: Highly regulated: Asian arowana (Scleropages formosus) is listed on CITES Appendix I. Only captive-bred fish with CITES papers and ID (microchip/certificate) may be kept or traded; local permits and rules vary—check before buying.

Care Level: Expert Only

Purchase Cost: $3,000 - $50,000
Lifetime Cost: $10,000 - $80,000

Economic Value

Uses:
Ornamental aquarium trade (luxury/high-value specimens, including 'platinum'/leucistic morphs) Captive-breeding industry (registered facilities, certification/traceability services) Cultural/ceremonial prestige value (status symbol; 'luck' associations in parts of Asia) Conservation enforcement economy (permitting, inspections, compliance, seizures)
Products:
  • Live fish (captive-bred, documented) for private aquaria
  • Breeding stock and juveniles from registered farms
  • Documentation packages (CITES permits, certificates, individual ID/microchip registration where used)
  • Specialty foods and husbandry equipment sized for large predatory, surface-dwelling fish (large tanks/ponds, heavy filtration, covers to prevent jumping)

Ecological Equivalents 5

Animals that fill a similar ecological role in their ecosystem

Silver arowana Osteoglossum bicirrhosum Very similar, surface-oriented predatory osteoglossid that patrols the upper water column and strikes prey at or above the surface; an ecological analogue in South America. Asian arowana is reported to reach a maximum length of 90.0 cm TL in FishBase, consistent with a comparable 'large, surface predator' niche.
Arapaima
Arapaima Arapaima gigas Large freshwater apex predator that relies on aerial respiration as an obligate air-breather and commonly feeds near the surface in slow waters. Overlaps the "large-bodied, air-breathing, surface-feeding predator" niche (different family within Osteoglossiformes).
Giant snakehead Channa micropeltes Southeast Asian large predatory fish of rivers and floodplains that often hunts in upper water layers and is capable of aerial respiration; it can occupy similar habitats and compete for fish and crustacean prey.
Banded archerfish Toxotes jaculatrix Surface-associated predator that targets insects and other prey at the air–water interface (a different size class), sharing the Asian arowana's emphasis on surface feeding, notably in brackish-to-fresh systems.
Giant gourami Osphronemus goramy Large-bodied, slow-water freshwater fish in Southeast Asia that regularly uses the surface as a labyrinth air-breather and overlaps in habitat (vegetated lowland rivers and swamps). It is more omnivorous than the primarily predatory Asian arowana.

Whatever type of arowana it is, this fish is prized for its extreme rarity and its breathtaking beauty.

For some connoisseurs of really exotic aquarium fish, the platinum arowana belongs to the species Osteoglossum bicirrhosum. For others, this fish, whose scales glitter like precious metal, is a member of the Scleropages formosus species. Anyone who wants one will have to pay the price, and not just in dollars. It is illegal to own a platinum arowana in the United States without a permit, and folks caught trying to smuggle one in can wind up behind bars.

Four Platinum Arowana facts

Here are some facts about this stunning and very expensive fish:

1. It can fetch a price of $300,000 and up.
2. Sometimes they are given plastic surgery to make them look even prettier.
3. Because arowanas resemble dragons, they are considered good luck in China.
4. Female arowanas are larger than males, but besides that they are very difficult to tell apart.
5. Scientists believe the reason that arowanas are found in Asia, Australia and South America is that they evolved while most of the earth was still basically one land mass. Arowanas are very ancient fish!

Platinum Arowana Classification and Scientific name

The platinum arowana is a mutation of several kinds of arowana fish. One belongs to the Scleropages formosus species. The genus name comes from the Greek word skleros, which means “hard” and the Latin word pages, which means “leaves.” This refers to the large, hard, beautiful scales over the fish’s body. Formosus is the Latin word for “beautiful.” Scleropages formosus has no subspecies, but color morphs are found in different areas of its range. They are the:

• Green
• Silver Asian
• Red-tailed golden
• Gold crossback
• Super red

The epithet of Scleropages inscriptus is Latin for “to write on” and describes the beautiful patterns on the scales of this fish from Myanmar. Scleropages jardinii and Scleropages leichardti are found in Australia. The former’s other names include the Gulf saratoga, the pearl arowana and the northern saratoga, while the latter’s other names include the southern saratoga, the spotted bonytongue and the barramundi.

Other names for Asian arowanas are monkey fish for its propensity to leap out of water to snatch its food, dragon fish, or lóng yú and Asian bonytongue.

Another type of platinum arowana is the silver platinum arowana, Osteoglossum bircurrhosum. The meaning of the genus means “bone-tongued” in Greek, and the epithet is Greek for “two barbels.” Like Asian arowanas, it can leap out of the water to catch its prey. Because of this, its other name is “water monkey.”

Platinum Arowana Appearance

The platinum arowana has a long, flat body that can grow up to 4 feet in length, with long dorsal, anal and pectoral fins. The caudal, or tail fin of the silver arowana is smaller than the tail fins of the Asian arowanas. The tail tapers elegantly, and the fish has a large, upturned mouth with many teeth, including teeth on the tongue. The most noticeable thing about the fish is its large scales, which are a shimmering platinum/silver all over the body. The scales can be as large as 0.79 inches in diameter. They are overlapping, smooth and disc shaped, and in some species the scales have beautiful raised patterns.

Platinum Arowana Distribution, Population, and Habitat

Platinum arowanas are found in bodies of fresh water in Asian countries such as Myanmar, the Philippines and Indonesia, in South American countries such as Colombia and Brazil and in Australia. They are found in locations such as slow rivers, flooded forests and swamps.

Platinum Arowana Predators and Prey

Besides humans, the predators of the platinum arowana are fish that are larger in size than it is. As for prey, the fish has been known to eat snakes, birds and bats, but it usually takes insects, smaller fishes, crustaceans and other animals that live on the surface of the water for its food.

Platinum Arowana Reproduction and Lifespan

Scientists who have seen arowana fish spawn notice that their courtship ritual can take weeks to months, with the mated pair swimming together near the surface of the water at night, circling, then swimming beside each other until the female deposits eggs into the water. These eggs are large, a shade of red or orange in the case of S. formosus and range from about 30 to 100. The male fertilizes them then scoops them into his mouth where they will stay until well after they hatch. The fry leave their father’s mouth after they’ve depleted their yolk sac, and this can take as long as two months.

Arowanas mature when they’re around three or four years old, which is late for fish. If they are kept in captivity and well-cared for, the lifespan of a platinum arowana can be about 20 years.

Platinum Arowana in fishing and cooking

Platinum arowana are so rare that they’re wanted almost exclusively for the pet trade, but silver arowana are sometimes used for food by people who live in the Brazilian rainforest. However, there are now restrictions on when the fish can be caught.

Platinum Arowana Population

Platinum arowana are so rare that some believe there are only a handful at any one time, and even the more typical Asian arowanas are considered endangered. The conservation status of the silver arowana of South America is still unevaluated.
