Arowana (Dragon Fish) Complete Care Guide for Qatar Aquarium Owners
Most aquarium fish are kept. Arowana are experienced. They recognise their owners. They approach the glass when you enter the room. They respond to feeding time with a slow, deliberate surface patrol that makes every other fish in the hobby look ordinary by comparison. Arowana fish Qatar hobbyists keep are not community tank fish, not beginner fish, and not affordable purchases.Â
The Silver Arowana (Osteoglossum bicirrhosum) is a prehistoric, surface-dwelling predator from the Amazon Basin. It grows to 90 to 100cm in captivity, requires a minimum 600-litre tank as an adult, needs a heater set to 24 to 27°C year-round in Qatar’s AC-cooled homes, and lives 15 to 20 years with correct care.
In Qatar, the Arowana carries additional significance. Called the Dragon Fish across much of Southeast Asia, it is considered a symbol of luck, prosperity, and good fortune – which explains its enduring popularity among Qatar’s large Chinese, Filipino, Malaysian, and Indian expat communities.
At World of Birds Qatar, we have been supplying Arowana to Doha customers since 1985. Our Souq Al Ali store stocks Silver Arowana with regular shipment arrivals. Browse our live freshwater fish collection to check current availability. In this blog, we’ll cover everything Qatar aquarium owners need to keep an Arowana alive and thriving for years.
Why Arowana (Dragon Fish) Are Qatar’s Most Prestigious Aquarium Fish
Arowana fish Qatar enthusiasts keep occupy a completely different category from every other species in this blog series. They are not bought on impulse. They are planned for, budgeted for, and prepared for over months. The tank must be ready before the fish arrives. The equipment must be running. The water must be conditioned and cycled.
And yet Qatar’s demand for Arowana has never been stronger.
The Arowana’s resemblance to the Chinese dragon – its elongated, scaled body, the barbels at the tip of its lower jaw, the way it glides through water with total control – makes it deeply significant to Qatar’s Chinese, Filipino, Malaysian, and Indian expat communities. In a country where these communities number in the hundreds of thousands, the dragon fish Qatar market is substantial and consistent.
At World of Birds, we have been supplying Arowana to Qatar customers since 1985. Over four decades, we have advised buyers on tank size requirements, watched the fish grow from juveniles to full adults, and seen the consequences when the setup is wrong. This guide covers everything you need to get it right.
If you are new to fish keeping, the Arowana is not your starting point. Read our beginner aquarium fish guide for Qatar first and return to Arowana after you have kept fish successfully for at least a year.

Silver Arowana vs Asian Arowana – Which Is Available in Qatar?
Qatar buyers searching for arowana fish Qatar frequently encounter two very different fish under the same name. Understanding the difference before purchasing prevents significant legal and financial problems.
Silver Arowana (Osteoglossum bicirrhosum) originates from South America’s Amazon Basin. It is legal to buy, sell, and keep worldwide without special permits. It is the most common and least expensive arowana you can find. Silver Arowana reach 90 to 100cm in captivity and are the variety World of Birds stocks regularly.Â
Asian Arowana (Scleropages formosus) originates from Southeast Asia and includes the iconic red dragon, golden dragon, and green varieties. Asian Arowanas are CITES Appendix I species.Â
For Qatar aquarium owners, Silver Arowana is the practical, legal, and accessible choice. The cultural symbolism – the dragon fish Qatar connection, the luck and prosperity significance – applies fully to Silver Arowana. Everything in this guide covers Silver Arowana care specifically.
What Size Tank Does an Arowana Need in Qatar?
A juvenile Silver Arowana needs a minimum 280 litres to start. Plan for 470 litres within 12 months and a minimum 600-litre adult tank no shorter than 2.4 metres in length before the fish outgrows its current home.
Arowana tank size is not negotiable. A tank that is too short forces the fish to curve its body constantly – this causes permanent spinal deformation that shortens the fish’s life and ruins its posture. The tank must be at least 2.4 metres long for an adult Silver Arowana to turn without stress.
Qatar-specific advantage: Doha’s large apartments and villas provide more space for a 600-litre+ tank than many housing situations in other countries. A wall-length aquarium cabinet in a Doha villa majlis is not unusual – and it is one of the most impressive displays possible in any private home. Browse large Aquariums and Stands at World of Birds for tank options suited to Arowana keeping.
Arowana Water Parameters – Temperature, pH, and Qatar Tap Water
Water quality management for arowana fish Qatar keepers is more demanding than for any other fish in this blog series. Arowanas can grow over 3 feet long and live 10 to 20+ years. Frequent water testing is essential as they are sensitive to water quality.
Ideal water parameters for Arowana in Qatar:
- Temperature: 24 to 27°C (heater essential)
- pH: 6.5 to 7.5
- Ammonia: 0 ppm (always)
- Nitrite: 0 ppm (always)
- Nitrate: below 20 ppm – Arowana are more sensitive to nitrate than most aquarium fish
- Water hardness: soft to moderate
Most Silver Arowana available in Qatar are captive-bred and more adaptable than wild-caught fish – Doha’s desalination tap water (slightly harder, slightly alkaline) is acceptable after conditioning. For a complete guide to maintaining water quality in your Qatar aquarium, read our aquarium water quality guide.
Does Arowana Need a Heater in Qatar?
Yes. Always. Without exception – and with redundancy.
Arowana water temperature must stay between 24 and 27°C. Qatar’s AC-cooled rooms maintain 20 to 23°C in summer and drop further in winter. Both scenarios fall below the minimum temperature Silver Arowana need to stay healthy.
The heater requirement for Arowana in Qatar goes beyond what we recommend for other tropical fish. A 600-litre tank requires two 300-watt heaters running simultaneously – one as the primary, one as a backup. A single heater failure in an unmonitored tank overnight can drop 600 litres of water from 26°C to dangerously low temperatures before morning. Dual heaters prevent this entirely.
Set both heaters to 26°C. Verify with a separate digital thermometer. Check temperature daily for the first month until you are confident in the system.
Filtration for Arowana in Qatar
A single adult Silver Arowana produces more biological waste than a community tank of 20 smaller fish.
Standard aquarium filters are inadequate for Arowana keeping. The filtration system must be sized for a fish that reaches 90 to 100cm and consumes large protein-rich meals. The general rule: filter turnover of at least 10 times the tank volume per hour. A 600-litre Arowana tank needs filtration rated at 6,000 litres per hour minimum.
Two canister filters running simultaneously is the recommended approach for Qatar Arowana setups – one provides the bulk of biological filtration, the second provides mechanical filtration and redundancy. If one filter fails, the second maintains the tank’s biological stability while the first is cleaned or repaired. Browse high-capacity aquarium filters at World of Birds for canister filter options suitable for large Arowana setups.
Why Weekly Water Changes Are Non-Negotiable for Arowana in Qatar
Accumulated nitrate causes chronic stress, reduced growth, and increased disease susceptibility in Arowana over months.
Change 30% of the tank water weekly. Always. Treat replacement water with conditioner before adding. Never clean filter media and perform a large water change in the same week – doing both simultaneously crashes the beneficial bacterial colony and causes ammonia spikes in a tank with a fish that is extremely sensitive to ammonia.
Qatar-specific: warm indoor environments accelerate waste decomposition. Monitor ammonia and nitrate weekly for the first 3 months of keeping Arowana. Increase water change frequency to twice weekly if nitrate climbs above 20 ppm.
Lighting for an Arowana Tank in Qatar
Lighting for Arowana tanks is not about plant growth or visual display. It is about preventing one of the most common and most heartbreaking Arowana health problems: drooping eyes.
Silver Arowanas commonly develop ventral strabismus – the eyes begin to droop downward from constantly looking toward the bottom of the tank or from bright overhead light causing stress. Once it develops, it is nearly irreversible. Prevention matters far more than treatment.
Use moderate LED lighting only. Run it 8 to 10 hours daily on a timer. Never use intense overhead lighting that causes the fish to consistently look downward. Avoid placing the tank where bright light sources exist below tank height – televisions, light-coloured tiled floors, reflective surfaces under the tank.
What to Feed Arowana in Qatar – Arowana Feeding Guide
Silver Arowana are obligate carnivores that evolved to hunt at the water’s surface. Their diet in the wild includes insects, small fish, crustaceans, amphibians, and occasionally small birds or mammals near the water.Â
Staple food: High-quality Arowana-specific pellets. These provide complete nutrition, reduce water fouling compared to live food, and ensure the fish receives consistent vitamins and minerals.Â
Supplement with: Frozen prawns (thaw in tank water first), small fish fillets, crickets, mealworms. Offer variety across the week – different protein sources prevent nutritional deficiency and maintain the fish’s interest in feeding.
Feeding schedule: Juveniles under 12 inches (30cm) once or twice daily. Adults over 24 inches (60cm) once every 1 to 2 days only – not multiple times per day. Overfeeding an adult Arowana causes fatty liver disease and swim bladder problems that are difficult to reverse.

Foods to Avoid Feeding Arowana in Qatar
- Goldfish feeder fish are the most dangerous food source.Â
- Wild-caught insects from Qatar’s outdoor environmentÂ
- Excessive prawns as the sole protein source
Weaning Arowana Onto Pellets in Qatar
Many Arowana arrive at Qatar shops eating live food only. Transitioning to pellets requires patience but is worth the effort – a pellet-eating Arowana is easier to feed consistently and has better long-term nutritional stability.
At our Souq Al Ali store, ask our staff what the specific Arowana has been eating before you purchase. A fish already eating pellets is significantly less work than one that requires live food transitioning.
Arowana Tank Mates – Which Fish Are Safe in Qatar?
The honest answer for most Qatar Arowana setups: no tank mates.
A solo Silver Arowana in a 600-litre tank is the most common and most successful setup for arowana fish Qatar keepers. It is the simplest to manage, produces the least water quality complexity, and allows the Arowana to be the undisputed centrepiece – which is the reason most Qatar buyers chose this fish in the first place.
Arowana tank mates are possible but add significant complexity. Any tank mate must be large enough not to be eaten, not aggressive enough to harass the Arowana’s fins or barbels, and able to tolerate the same water parameters.
Species that work with Silver Arowana in large Qatar tanks (800 litres+):
- Oscars (20cm+) – South American cichlids that share Arowana water parameters and are large enough to avoid being eaten.
- Plecos (Hypostomus species, 30cm+) – bottom-dwelling armoured catfish that Arowana typically ignore entirely.
- Large Bichirs – prehistoric-looking bottom dwellers that occupy a completely different tank zone from surface-swimming Arowana.
Fish to never keep with Arowana:
Any fish under 15cm will be viewed as food. This eliminates Guppies, Tetras, Danios, Angelfish, Corydoras, and every species in the beginner fish category. Tiger Barbs fin-nip Arowana barbels – causing stress and infection. Betta Fish share no compatible conditions with Arowana.

Can You Keep Two Arowana Together in Qatar?
Two Silver Arowana in the same tank will establish dominance – one fish will dominate feeding, stress the other, and the subordinate fish declines progressively. The only exception is an extremely large tank (1,500 litres+) with multiple visual barriers and feeding stations. For standard Qatar home aquarium setups, one Arowana per tank is the rule without exception.
Common Arowana Health Problems in Qatar
Prevention is the only reliable approach for Arowana health. These are large, expensive, long-lived fish – treatment is difficult, stressful for the fish, and frequently unsuccessful once disease is established.
- Drooping Eyes (Ventral Strabismus) – The Most Preventable Arowana Problem
- Jump Injuries – The Qatar Lid Requirement
- Fin Rot and Scale Drop
- Swim Bladder Disease
- Ich (White Spot) – The Qatar AC Risk
How Long Do Arowana Live With Proper Care?
Silver Arowana live 15 to 20 years with correct care. Under the right circumstances, they can go past this age and live into their mid-twenties.
This is not a 3-year goldfish. This is not a 5-year Betta. Buying arowana fish Qatar hobbyists commit to is a 15 to 20-year decision that parallels the commitment of keeping a cat or dog.
What extends arowana lifespan: 600-litre+ tank, dual heaters at 26°C year-round, weekly 30% water changes, varied carnivore diet fed every 1 to 2 days for adults, secure weighted lid, moderate lighting, no bright reflections below tank height.
At our Souq Al Ali store, we have customers who purchased Silver Arowana from us years ago returning to discuss tank upgrades as their fish approaches full adult size. That is the best possible outcome – a fish that is growing correctly because the setup was done right from the beginning.

Frequently Asked Questions About Arowana Fish in Qatar
What size tank does an Arowana need in Qatar?
A juvenile arowana fish Qatar buyers purchase (typically 10 to 15cm) can start in a 200 to 280-litre grow-out tank. Plan for 470 litres within 6 to 12 months and a minimum 600-litre adult tank with a length of at least 2.4 metres. Under optimal conditions, Silver Arowana juveniles grow approximately 2 inches (5cm) per month in the first year.
What do Arowana fish eat in Qatar?
Arowana feeding in Qatar aquariums should centre on high-quality Arowana pellets as the staple food, supplemented with frozen prawns, small fish fillets, crickets, and mealworms. Feed juveniles under 30cm once or twice daily. Feed adults over 60cm once every 1 to 2 days only – overfeeding adult Arowana causes fatty liver disease that is difficult to reverse.
Does Arowana need a heater in Qatar?
Yes – and with redundancy. Silver arowana care requires water at 24 to 27°C. Qatar’s AC-cooled rooms maintain 20 to 23°C, well below Arowana’s minimum. A 600-litre Arowana tank in Qatar needs two 300-watt heaters running simultaneously. If one fails, the backup maintains temperature until the primary is replaced.
How long do Arowana fish live?
Arowana lifespan with correct care is 15 to 20 years, potentially reaching the mid-twenties under exceptional conditions. This is a long-term commitment equivalent to keeping a cat or dog. Before purchasing, confirm you can provide a 600-litre+ tank, weekly water changes, a quality diet, and stable temperature for the fish’s full life expectancy.
