Understanding the Allure: Why Choose an Arowana Fish as Pet?

So, what makes the arowana fish as pet such a coveted centerpiece for serious aquarists? It’s more than just their shimmering scales and imposing size. Arowanas possess a unique combination of characteristics that make them truly special.

For starters, their appearance is simply breathtaking. Often called “dragon fish” due to their large, metallic scales and barbels resembling a dragon’s whiskers, they command attention. Watching them glide effortlessly through the water is a mesmerizing experience, bringing a dynamic, wild beauty right into your living space. This is one of the primary benefits of arowana fish as pet—they are living works of art.

Beyond their looks, Arowanas are known for their intelligence and personality. They can recognize their owners, react to their presence, and even be hand-fed. This interactive element creates a strong bond, making them far more than just decorative additions to a tank. They become genuine companions, offering years of enjoyment. With proper care, these fish can live for 10-20 years, making them a long-term commitment and a truly enduring joy.

The Essential Habitat: Setting Up for Success

When it comes to housing an arowana fish as pet, their environment is paramount. These fish grow large, are powerful jumpers, and produce a significant bio-load. Neglecting tank size or filtration will lead to stress and health issues. Our arowana fish as pet care guide starts here: getting the habitat right from day one.

Tank Size & Placement: Go Big or Go Home

This is perhaps the single most critical factor. Arowanas are active, predatory fish that need ample swimming space. A juvenile Arowana might start small, but it will grow rapidly. You absolutely cannot skimp on tank size.

  • Minimum for Juveniles: Start with at least a 75-gallon (280 liters) tank for a young Arowana (under 10 inches). This gives them room to grow for a few months.
  • Minimum for Adults: For an adult Arowana (which can reach 2-3 feet in length depending on species), you’ll need a tank of at least 250-300 gallons (940-1135 liters), with 500 gallons (1890 liters) or more being ideal. Length and width are more important than height. Aim for a tank at least 8 feet long and 2.5-3 feet wide.
  • Placement: Choose a sturdy stand on a level surface, away from direct sunlight and high-traffic areas to minimize stress.
  • Secure Lid: Arowanas are incredible jumpers! A heavy, tightly fitting lid with no gaps is non-negotiable to prevent your prized pet from leaping out.

Filtration & Water Quality: The Lifeblood of Your Arowana

Arowanas are messy eaters and produce a lot of waste, so robust filtration is essential for maintaining pristine water quality—a cornerstone of arowana fish as pet best practices.

  • Over-filtration is Key: Don’t just meet the recommended filter size; exceed it. Aim for a filter system rated for at least twice the volume of your tank.
  • Multiple Filters: A combination of external canister filters, sumps, or even large hang-on-back filters (HOBs) is often recommended. This provides excellent mechanical, chemical, and biological filtration.
  • Water Flow: Arowanas appreciate moderate water flow, which helps oxygenate the water and prevents stagnant areas.
  • Air Stone/Powerhead: Consider adding an air stone or a small powerhead to boost oxygen levels, especially in larger tanks.

Heating & Lighting: Comfort and Stability

Maintaining stable water temperature is crucial for the health of your arowana fish as pet.

  • Temperature: Keep the water temperature consistently between 75-82°F (24-28°C). Use multiple heaters for larger tanks to ensure even heating and provide a backup in case one fails.
  • Lighting: Arowanas don’t have specific lighting requirements beyond what’s needed for viewing and, if applicable, for live plants. Standard aquarium LED or fluorescent lights are usually sufficient. Avoid excessively bright or prolonged lighting, as it can stress the fish.

Substrate & Decor: Safety First!

When decorating your Arowana tank, prioritize safety and open swimming space.

  • Substrate: A fine sand substrate is generally preferred, as Arowanas can sometimes injure themselves on sharp gravel. A bare bottom tank is also an option, making cleaning easier.
  • Decor: Keep decor minimal. Large, smooth rocks or driftwood can provide visual interest and security, but ensure they have no sharp edges and are firmly secured so they won’t topple over. Remember, your Arowana needs plenty of room to turn around without bumping into obstacles.
  • Background: A dark background can help your Arowana feel more secure and can also enhance their coloration.

Feeding Your Apex Predator: Nutrition for a Thriving Arowana

Feeding your arowana fish as pet is one of the most exciting aspects of their care, but it requires a careful approach to ensure balanced nutrition. Arowanas are carnivorous predators, and their diet should reflect this.

What to Feed: A Varied Carnivorous Diet

Variety is the spice of life, and it’s essential for a healthy Arowana. Don’t rely on just one food source.

  • Staple Foods: High-quality Arowana pellets or sticks should form the foundation of their diet. Look for brands with high protein content.
  • Live Foods (with caution): Feeder fish (guppies, mollies – quarantined to prevent disease), ghost shrimp, mealworms, superworms, crickets, and even small frogs can be offered. Be cautious about the source of live feeders to avoid introducing parasites or diseases.
  • Frozen Foods: Krill, silversides, bloodworms, and prawns are excellent frozen options. Thaw them completely before feeding.
  • Prepared Foods: Some aquarists prepare their own fish foods, often a mix of seafood, vitamins, and binders. This is an advanced option but can ensure complete nutrition.

Avoid feeding fatty meats like beef heart too frequently, as they can lead to health issues over time. Focus on lean, high-protein options.

Feeding Schedule: Consistency is Key

The frequency and amount of feeding will depend on the age and size of your arowana fish as pet.

  • Juveniles: Young Arowanas grow rapidly and should be fed 2-3 times a day, small amounts they can consume in a few minutes.
  • Adults: Mature Arowanas can be fed once a day or even every other day. Observe your fish; if they look full or refuse food, adjust accordingly.
  • Avoid Overfeeding: Overfeeding not only pollutes the tank but can also lead to digestive issues and obesity in your Arowana.

Water Chemistry & Maintenance: Keeping Conditions Pristine

Maintaining stable and clean water conditions is non-negotiable for the long-term health of your arowana fish as pet. This section of our arowana fish as pet guide details the crucial parameters and routines.

Essential Water Parameters

Regular testing is vital to ensure your water parameters are within acceptable ranges.

  • pH: Most Arowana species prefer slightly acidic to neutral water, typically pH 6.0-7.5. Avoid drastic fluctuations.
  • Ammonia & Nitrite: These should always be at 0 ppm (parts per million). Even trace amounts are toxic to Arowanas.
  • Nitrate: Keep nitrates below 20 ppm. While less toxic than ammonia and nitrite, high nitrates indicate poor water quality and can stress your fish.
  • GH & KH: General Hardness (GH) and Carbonate Hardness (KH) should be moderate. GH around 4-10 dGH and KH around 3-8 dKH is generally suitable.

The Importance of Regular Water Changes

Water changes are the most effective way to remove accumulated nitrates, replenish essential minerals, and maintain overall water quality.

  • Frequency: For a well-filtered Arowana tank, aim for a 25-30% water change weekly. If your tank is heavily stocked or you’re struggling with parameters, you might need to do more frequent or larger changes.
  • Temperature Matching: Always use dechlorinated water that is close to the tank’s existing temperature to avoid shocking your fish.
  • Gravel Vacuuming: Even with a bare bottom, vacuuming the bottom during water changes helps remove uneaten food and waste.

Common Problems with Arowana Fish as Pet & How to Solve Them

Even with the best intentions and diligent care, you might encounter some common problems with arowana fish as pet. Being prepared and knowing how to respond can make all the difference.

  • Drop Eye: This condition, where one or both eyes droop downwards, is common in captive Arowanas. While its exact cause is debated, it’s often linked to diet (too much floating food causing the fish to constantly look down), lack of stimulation, or genetics.
    • Prevention: Offer a varied diet with sinking foods, provide environmental enrichment, and ensure adequate swimming space.
    • Treatment: In some cases, adjusting the diet and environment can help, but it’s often irreversible. Some aquarists resort to surgical procedures, but these are risky.
  • Fin Rot & Other Bacterial Infections: These usually stem from poor water quality, stress, or injury.
    • Symptoms: Frayed, discolored, or disintegrating fins; lethargy; clamped fins.
    • Treatment: Immediately improve water quality with frequent partial water changes. Mild cases may resolve with improved conditions. More severe cases might require antibiotics (consult a vet or experienced fish store for appropriate medication).
  • Stress: Arowanas can get stressed by poor water quality, unsuitable tank mates, sudden changes in environment, or constant disturbances.
    • Symptoms: Hiding, loss of appetite, dull coloration, erratic swimming, rubbing against decor.
    • Treatment: Identify and eliminate the stressor. Ensure stable water parameters, provide hiding spots, and maintain a peaceful environment.
  • Jumping: Arowanas are natural jumpers, especially when startled, hunting, or stressed.
    • Prevention: A tightly fitting, heavy lid with no gaps is your best defense. Keep the tank in a quiet area.

Ethical & Sustainable Arowana Keeping

As responsible aquarists, considering the ethics and sustainability of keeping an arowana fish as pet is crucial. Many Arowana species are endangered or protected, making responsible sourcing a key part of sustainable arowana fish as pet practices.

  • Source Responsibly: Always purchase Arowanas from reputable dealers who can provide proof of legal sourcing. Look for captive-bred specimens whenever possible, especially for protected species like Asian Arowanas (which require CITES permits for international trade).
  • Long-Term Commitment: Understand that an Arowana is a long-lived fish requiring a large, dedicated tank for many years. Be prepared for the financial and time commitment involved.
  • Avoid Wild-Caught if Possible: Opting for captive-bred fish reduces pressure on wild populations, contributing to eco-friendly arowana fish as pet keeping.

Advanced Arowana Fish as Pet Tips for Long-Term Health

Beyond the basics, there are several “pro” tips that can elevate your Arowana keeping experience and ensure your fish thrives for years to come. These are some of the best arowana fish as pet best practices.

  • Tank Security is Paramount: We mentioned the lid, but reinforce it. Consider securing it with clamps or weights. A determined Arowana can exert surprising force.
  • Observational Skills: Spend time simply observing your Arowana. Learn its normal behaviors, swimming patterns, and eating habits. Subtle changes can be the first sign of an issue, allowing you to intervene early.
  • Enrichment: While Arowanas appreciate open space, occasional changes to decor (large, smooth items) or introducing new food items can provide mental stimulation.
  • Power Outage Plan: Have a battery-powered air pump and a plan for maintaining temperature during power outages, especially if you live in an area prone to them. Large fish are more susceptible to oxygen depletion.
  • Quarantine New Additions: If you plan on adding tank mates (which should be done with extreme caution for Arowanas), always quarantine new fish in a separate tank for several weeks to prevent introducing diseases.
