屬性
Often called a "living fossil," the arowana has remained virtually unchanged for approximately 200 million years and is found across Asia, South America, and Australia. The Asian arowana (Scleropages formosus), native to Southeast Asia, is especially prized for its stunning color varieties—golden, red, and green—and has long been regarded as a symbol of good fortune and prosperity. Its large, lustrous scales create an almost armor-like appearance, and watching it glide effortlessly near the water's surface delivers a sense of majesty unlike any other aquarium fish. While temperament varies between individuals, arowanas generally have strong territorial instincts yet tend to bond closely with their keepers over time. For dedicated aquarists, the combination of extraordinary longevity and an unmatched presence makes the arowana one of the most rewarding fish to keep for a lifetime.
1Massive Tank Required
Adult arowanas can reach 60–90 cm, so a tank at least 180 cm wide is typically required. It is advisable to plan for adult size from the start rather than upgrading tanks repeatedly. Tank setups of this scale can exceed 200 kg, so check that your floor can support the weight beforehand.
2Watch Out for Jumping
Arowanas are powerful jumpers and escaping the tank is a common and fatal accident. Always use a well-fitting, securely fastened lid with no gaps. Take extra care during feeding and water changes to avoid leaving the tank open.
3Best Kept Alone
Arowanas are territorial and may attack tankmates, so single-specimen keeping is generally recommended. If mixing with other fish, choose species larger or faster than the arowana and ensure ample space. Individual temperaments vary, so introduce tankmates gradually and monitor closely.
4Water Quality Is Critical
Arowanas prefer soft, slightly acidic to neutral water (pH 6.5–7.5). As large fish, they produce significant waste, making a powerful filtration system and regular water changes essential. Sudden changes in water parameters can cause stress or illness, so always match temperature and chemistry when doing water changes.
5Check Legal Regulations
Asian arowanas (distinct from silver arowanas) are regulated under CITES (the Washington Convention), and trading or importing them without proper documentation is illegal. Always verify the species and supply chain before purchasing and obtain fish through legitimate channels. Regulations can change, so stay informed of the latest rules.

Care difficulty, lifespan, size and diet — all basics covered.
6Offer a Varied Diet
Arowanas are carnivores that naturally prefer live food such as insects, crustaceans, small fish, and earthworms. A diet of only live food may lack balance, so gradually training them to accept prepared pellets is recommended. Feed once or twice daily in amounts that leave no waste to protect water quality.
7Plan for Long-Term Costs
Beyond the initial purchase price of the fish, setup costs for a large tank, powerful filter, heater, and other equipment can be substantial. With a lifespan of 20–30 years, ongoing costs for electricity, food, and consumables add up significantly over time. Calculate the total long-term cost before committing to ownership.
