Arowana are among the most prestigious freshwater aquarium fish in the world. Before purchasing online, understand legal status, tank size, cost, and long term care requirements.
Arowana are large, surface dwelling freshwater fish known for metallic scales, elongated bodies, and powerful jumping ability, often called Dragon Fish.
Arowana belong to the family Osteoglossidae and are native to tropical regions of South America, Asia, and Australia. Their upturned mouths and barbels help them hunt insects and small prey near the water surface.
Arowana inhabit warm, slow moving rivers, swamps, and floodplains across South America, Southeast Asia, and northern Australia.
Species such as the Silver Arowana from the Amazon basin and Asian varieties from Southeast Asia evolved in soft, slightly acidic water with seasonal flooding cycles.
The main Arowana types are Silver, Asian, Australian, and Black, each differing in origin, coloration, size, rarity, and price.
Native to South America, these are the most commonly available and affordable species.
Often called the Super Red or Golden Arowana, these are highly valued and regulated internationally.
Known for pearl like spotting and strong body structure, native to northern Australia.
Juveniles display striking dark coloration and originate from the Amazon region.
Arowana prices range from a few hundred dollars for Silver varieties to several thousand dollars for rare Asian strains.
Pricing depends on species, size, coloration, lineage certification, and legal documentation. Asian Arowana are typically the most expensive due to restricted trade status and breeding controls.
Ongoing ownership costs include:
Asian Arowana are protected under the Convention on International Trade in Endangered Species CITES, and require proper certification for legal trade.
Some countries restrict or prohibit importation. Always verify local regulations and ensure the seller provides valid documentation before purchasing.
Silver and Australian Arowana are generally less restricted, though local laws still apply.
Arowana require a minimum 120 gallon aquarium, though 180 gallons or larger is recommended for adult specimens.
These fish can grow over 90 cm depending on species. Tanks must include:
Underestimating tank size is one of the most common beginner mistakes.
Arowana thrive in warm water between 24 and 28°C with a pH range of 6.0 to 7.5 and strong filtration.
Stable parameters are more important than chasing exact numbers. Weekly partial water changes help prevent ammonia buildup and stress related illness.
Arowana are carnivorous predators that require a high protein diet of insects, shrimp, fish, and quality formulated pellets.
Feeding tips:
Arowana are territorial and predatory, but not typically aggressive toward similarly sized tank mates.
Compatible companions may include:
Small fish will likely be eaten. Many keepers prefer housing Arowana alone.
Arowana are mouthbrooders, meaning the male carries fertilized eggs in his mouth until the fry hatch.
Breeding typically requires:
Captive breeding of Asian Arowana is tightly controlled in many regions.
Common Arowana health issues include dropsy, ich, fin rot, and swim bladder problems, often linked to poor water quality.
Warning signs:
Preventative care through filtration, stable temperature, and proper diet is more effective than reactive treatment.
Arowana typically live 10 to 15 years in captivity, and may live longer with excellent care and spacious housing.
Longevity depends on:
They are a long term commitment rather than a short term aquarium addition.
Buy Arowana online only from reputable breeders who provide health guarantees, clear photos, legal documentation, and secure live shipping practices.
Before purchasing:
Never purchase undocumented protected species.
Some species, particularly Asian Arowana, face conservation pressure due to habitat loss and overcollection, leading to international trade regulation.
Supporting responsible breeders and verified captive bred sources reduces pressure on wild populations.
Arowana fish are striking, intelligent, and commanding aquarium predators that require space, stability, and responsible ownership.
Before buying online, confirm legal requirements, prepare an adequately sized tank, and understand the long term financial and care commitment.
With proper preparation, an Arowana can become the centerpiece of a large freshwater aquarium for over a decade.
