Unveiling the Majesty: Arowana Fish Species Demystified
The term “arowana” often conjures images of powerful, ancient fish, and for good reason. These osteoglossids, often called “bony tongues” due to a unique bone structure in their mouths, have roamed Earth’s waters for millions of years. Their sleek bodies, large scales, and distinct predatory mouths make them truly captivating.
When we talk about arowana fish species, we’re actually referring to several distinct types, each with its own charm and specific care requirements. Understanding these differences is your first step towards becoming an expert arowana keeper.
The Allure of Arowanas
What makes arowanas so special? Beyond their striking appearance, they possess an intelligence and personality that many fish lack. They can recognize their owners, react to their presence, and even be hand-fed. This interactive quality is one of the many benefits of arowana fish species ownership, creating a bond unlike any other with an aquatic pet.
They are also incredibly active swimmers, patrolling their tanks with an almost regal grace. Witnessing their natural behaviors, from hunting to interacting with their environment, is a continuous source of fascination.
Popular Arowana Fish Species for Your Aquarium
While there are several types of arowanas globally, a few stand out as common choices for home aquariums. It’s crucial to research each one before making a commitment.
- Silver Arowana (Osteoglossum bicirrhosum): Often considered the entry-level arowana due to its relative affordability and availability. Hailing from the Amazon, these beauties can reach over three feet in captivity! They are known for their metallic silver scales and energetic swimming. If you’re looking for how to arowana fish species care for a beginner-friendly option, the Silver Arowana is a fantastic starting point.
- Asian Arowana (Scleropages formosus): These are the true “dragon fish” revered in Asian cultures for bringing luck and prosperity. They come in stunning varieties like Red Arowana, Gold Arowana, and Green Arowana. Asian Arowanas are CITES Appendix I protected, meaning they are endangered and require strict legal documentation (microchip, certification) for ownership. They are significantly more expensive and require specialized care.
- Jardini Arowana (Scleropages jardinii): Also known as the Australian Arowana or Gulf Saratoga, this species features a unique spotted pattern on its scales. They are hardy and can be a good choice for those looking for something a bit different from the Silver Arowana, though they can be quite aggressive.
- Australian Pearl Arowana (Scleropages leichardti): Similar to the Jardini, but often with more distinct red spots, giving them a “pearl” effect. They share many care similarities with the Jardini.
- Black Arowana (Osteoglossum ferreirai): A stunning, albeit rarer, relative of the Silver Arowana, found in the Rio Negro. Juveniles are strikingly black with yellow markings, which fade to a darker silver as they mature.
Always ensure you are sourcing your arowana legally and ethically, especially for protected species. We’ll delve deeper into sustainable arowana fish species practices later on.
Setting Up for Success: Arowana Fish Species Best Practices for Tank Environment
Providing the right environment is paramount for any fish, and for large, active predators like arowanas, it’s absolutely critical. Think of it as building a luxury apartment for a high-end tenant. This section is your essential arowana fish species care guide for their home.
Tank Size: Go Big or Go Home!
This isn’t just a suggestion; it’s a rule. Arowanas grow *very* large, and quickly. A common mistake is starting with a tank that’s too small, leading to stunted growth, stress, and behavioral issues. For a single Silver Arowana, you’ll need a minimum of 250 gallons (approx. 950 liters), but 300-500 gallons is truly ideal for adult specimens. For Asian Arowanas, similar or even larger tanks are recommended.
The tank should also be long and wide, not just tall. A minimum length of 8 feet (240 cm) and a width of at least 2.5 feet (75 cm) is crucial to allow them ample turning space and swimming room. Remember, a bigger tank offers more stable water parameters, which is a huge plus!
Filtration: Crystal Clear Waters are Key
Arowanas are messy eaters and produce a significant bio-load. Therefore, a robust filtration system is non-negotiable. You’ll need multiple layers of filtration:
- Mechanical Filtration: To remove physical debris like uneaten food and waste. Large canister filters, sumps, or even sponge filters can contribute.
- Biological Filtration: Essential for converting harmful ammonia and nitrites into less toxic nitrates. Bio-media in canister filters or a well-designed sump system with bio-balls or ceramic rings are excellent.
- Chemical Filtration: Activated carbon can help remove odors and discoloration, keeping the water sparkling. Replace it regularly.
Aim for a total filtration turnover rate of at least 5-10 times the tank volume per hour. Over-filtering is always better than under-filtering when it comes to arowanas.
Substrate and Decor: Creating a Natural Habitat
Keep it simple and safe. Arowanas are powerful and can easily injure themselves on sharp objects. Smooth, fine gravel or sand is suitable, but many experienced keepers opt for a bare bottom tank for easier cleaning.
Decorations should be minimal and secure. Large, smooth river rocks or well-anchored driftwood can provide visual interest and security. Ensure there are no sharp edges or narrow spaces where your arowana could get stuck. Floating plants can help diffuse light and provide a sense of cover, but they may be uprooted.
And remember, arowanas are jumpers! A heavy, secure lid is not just recommended, it’s absolutely essential to prevent your prized fish from leaping out of the tank.
Water Parameters: The Science of Serenity
Consistent, stable water parameters are vital for your arowana’s health. Here are the ideal ranges:
- Temperature: 75-82°F (24-28°C). Use reliable heaters with guards to prevent burns.
- pH: 6.0-7.5 (slightly acidic to neutral). While Silver Arowanas are somewhat tolerant, Asian Arowanas prefer slightly softer, more acidic water.
- Hardness: 5-12 dGH (soft to moderately hard).
- Ammonia, Nitrite: 0 ppm. These are highly toxic.
- Nitrate: Below 20 ppm. Regular water changes are your best friend for keeping nitrates low.
Perform weekly water changes of 20-30% using dechlorinated water. This is one of the most important arowana fish species tips you’ll ever receive. Consistent water quality prevents stress and disease, keeping your magnificent fish happy.
Feeding Your Dragon: Arowana Fish Species Tips for a Thriving Diet
Arowanas are obligate carnivores with a voracious appetite. Providing a balanced and varied diet is crucial for their growth, coloration, and overall health. Think of yourself as their personal chef!
What to Feed: Variety is the Spice of Life
Arowanas are opportunistic predators in the wild, eating insects, small fish, and even small birds or mammals that fall into the water. In captivity, you should mimic this diversity:
- Staple Foods: High-quality arowana pellets or sticks should form the base of their diet. Look for brands specifically formulated for large carnivorous fish.
- Live Foods (with caution): Crickets, mealworms, grasshoppers, and earthworms are excellent. Feeder fish (like guppies or mollies) can be offered sparingly, but always quarantine them first to avoid introducing diseases. Avoid goldfish, as they are high in thiaminase, which can be harmful long-term.
- Frozen Foods: Krill, silversides, shrimp, and even pieces of white fish (like tilapia or cod) are fantastic options. Thaw thoroughly before feeding.
- Other Treats: Occasionally, you can offer small pieces of lean chicken or beef heart, but these should be very rare treats due to their fat content.
Avoid feeding only one type of food. A varied diet ensures your arowana receives all necessary nutrients, leading to vibrant colors and strong growth.
Feeding Frequency and Portions
Juvenile arowanas (under 10 inches) should be fed 2-3 times a day, as much as they can eat in a few minutes. As they grow larger, reduce feeding to once a day, and then to once every other day for very large adults.
The key is to observe your fish. If their belly looks slightly rounded after feeding, that’s a good sign. If it’s distended, you’ve fed too much. Always remove any uneaten food immediately to prevent water quality issues.
Live vs. Prepared Foods: Balancing Nutrition and Risk
While live foods certainly trigger their natural hunting instincts and provide enrichment, they also carry risks. Live feeder fish can introduce parasites or diseases into your tank. If you choose to feed live fish, source them from a reputable supplier and ideally, quarantine them in a separate tank for a week or two, feeding them high-quality food to “gut load” them before offering them to your arowana.
For convenience and safety, many aquarists rely heavily on a combination of high-quality pellets and frozen foods. This approach minimizes health risks while still providing excellent nutrition. This is part of the arowana fish species best practices for diet.
Maintaining Health: Common Problems with Arowana Fish Species and How to Solve Them
Even with the best care, sometimes things go wrong. Being aware of common problems with arowana fish species and knowing how to address them quickly can save your fish. Early detection is key!
Fin Rot and Fungal Infections
These are often stress-related or a symptom of poor water quality. Fins may appear frayed, discolored, or have cotton-like growths.
Solution: Immediately perform a large water change (30-50%) and ensure your filtration is optimal. Mild cases can often resolve with pristine water. For more severe infections, consult your local fish store or an aquatic veterinarian for appropriate medication (e.g., broad-spectrum antibiotics or antifungal treatments).
Drop Eye: A Common Arowana Ailment
This condition, where one or both eyes sag downwards, is prevalent in arowanas, particularly Silver Arowanas. While its exact cause is debated, common theories include:
- Diet: High-fat diets, especially from feeding live feeder fish that swim at the bottom.
- Tank Environment: Looking down constantly at a bare bottom or at activity outside the tank.
Solution:
- Adjust diet: Reduce fatty foods, offer more floating foods.
- Environmental changes: Use a dark substrate, add a floating ping-pong ball or toy to encourage upward gaze, or even block external views below eye level.
Drop eye is largely aesthetic and doesn’t usually harm the fish, but prevention is better than trying to reverse it.
Gill Curl and Other Physical Deformities
Gill curl occurs when the gill plate curls outwards, often due to poor water quality or rapid growth spurts in a tank that’s too small. This can impede breathing.
Solution: Improve water quality drastically with large, frequent water changes. Ensure the tank is appropriately sized. In severe cases, surgical trimming by an experienced professional might be an option, but prevention is always preferable.
Other deformities, like bent spines, are often linked to genetics, poor nutrition during development, or inadequate tank size and water quality leading to stunted growth.
Preventing Stress and Disease
Prevention is the best medicine for your arowana fish species. Here’s how:
- Stable Environment: Maintain consistent water parameters, temperature, and a large, appropriately decorated tank.
- Quality Diet: Offer a varied, nutritious diet.
- Regular Maintenance: Perform consistent water changes and filter cleaning.
- Observation: Spend time watching your fish daily. Changes in behavior, appetite, or appearance are early warning signs.
- Quarantine: Always quarantine new fish, plants, or live foods before introducing them to your main tank.
A healthy, well-cared-for arowana is a resilient one!

This sense of achievement motivates you to continue learning and improving, pushing your hobby to new and exciting levels.
Responsible Arowana Ownership: Sustainable and Eco-Friendly Approaches
With their popularity, especially the highly coveted Asian Arowana, comes the responsibility of ethical and sustainable arowana fish species ownership. Being a responsible aquarist means considering the broader impact of your hobby.
Sourcing Your Arowana Ethically
Always purchase your arowana from reputable breeders or dealers who can provide documentation of their origin. For Asian Arowanas, this means CITES certificates and microchip identification. This ensures your fish was legally bred in captivity and not wild-caught, which helps protect wild populations.
Inquire about the breeder’s practices. Do they prioritize the health and well-being of their fish? Do they adhere to ethical breeding standards? Supporting responsible sources is key to eco-friendly arowana fish species keeping.
Understanding CITES and Legalities
The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) lists many arowana species, particularly Asian Arowanas, as endangered. This means their trade is strictly regulated to prevent extinction.
If you’re considering an Asian Arowana, you *must* understand and comply with all local and international laws regarding their ownership. This typically involves microchipping and official documentation. Without proper papers, you could face legal consequences and contribute to illegal wildlife trade.
Long-Term Commitment and Planning
An arowana is a long-term commitment. These fish can live for 10-20 years or more with proper care. Before bringing one home, consider:
- Space: Do you have the space for an adult-sized tank (300+ gallons)?
- Cost: Can you afford the initial setup, ongoing food, electricity (for heaters/filters), and potential veterinary care?
- Time: Are you committed to the daily feeding and weekly maintenance?
- Future: What happens if you move or your circumstances change? Have a contingency plan.
Responsible ownership means being prepared for the entire lifespan of your magnificent pet. This is truly the essence of arowana fish species best practices.
Frequently Asked Questions About Arowana Fish Species
Let’s tackle some of the most common queries about these incredible fish.
Are Arowana fish species aggressive?
Generally, arowanas are predatory but not inherently aggressive towards tank mates that are too large to be considered food. However, they can be territorial towards other large fish, especially other arowanas. Keeping them with similarly sized, robust, non-aggressive species is often recommended if you plan a community tank. Many aquarists opt for a single arowana to avoid potential conflicts.
How long do Arowana fish species live?
With proper care, arowanas can live a remarkably long time. Silver Arowanas typically live 10-15 years, while some Asian Arowanas have been known to live for 20 years or even longer in ideal conditions. This is why long-term commitment is so important!
Can I keep different arowana fish species together?
It’s generally not recommended to keep different arowana fish species together, especially in smaller tanks. They are highly territorial and can become aggressive towards each other, leading to injuries or even death. If attempting to keep multiple arowanas, it requires an extremely large tank (thousands of gallons) and careful monitoring, usually only by very experienced aquarists.
What’s the best way to transport an Arowana?
Transporting an arowana requires extreme care due to their size and stress sensitivity. They should be transported in a large, dark, sturdy bag or container with plenty of oxygenated water. Minimize handling and movement, and keep the journey as short as possible. For very large specimens, professional transport services are often the safest option.
Do Arowanas jump?
Yes, absolutely! Arowanas are renowned for their jumping ability, which they use in the wild to catch insects and small animals from overhanging branches. This means a very heavy, secure, and tightly fitting lid is non-negotiable for any arowana tank. Even small gaps can be an escape route, so double-check your lid’s security!
