Can Arowana Live with Oscar? (2024)

In the intricate world of fishkeeping, the allure of combining different species in a single aquarium is a tempting endeavor for many. It’s not just about conserving space or creating an eclectic underwater community; it’s about watching diverse personalities interact and creating an underwater tapestry of colors, movements, and behaviors.

Arowana and the Oscar fish can live together well. Both are treasured for their commanding presence, unique personalities, and sheer size. Before you embark on the journey of introducing these two species into a shared environment, let’s dive deep and explore the dynamics, needs, and potential challenges of housing Arowanas and Oscars together.

Can Arowana Live with Oscar?

Fishkeeping enthusiasts are often intrigued by the possibility of pairing various fish species together, either for aesthetics or to better utilize tank space. But, the million-dollar question we’re tackling today is: Can an Arowana and an Oscar share the same tank? The short answer: Yes, however, It’s tricky and comes with several caveats. But let’s dive deeper into the dynamics of these two majestic fish and the environment they thrive.

Arowana and Oscar: Interaction

Arowanas and Oscars are both large, charismatic, and incredibly popular in the fishkeeping world. But does this mean they can live harmoniously together?

To begin with, Arowanas, often referred to as “dragon fish,” are powerful and agile swimmers. They’re known for their shimmering scales and the way they gracefully skim the water’s surface, waiting to pounce on unsuspecting prey.

Oscars, on the other hand, are stockier, with a more aggressive disposition. They’re characterised by their vibrant patterns and an almost dog-like personality, often interacting playfully with their owners.

Size is the first factor to consider. A full-grown Arowana can reach lengths of up to 3 feet, whereas Oscars typically max out at about 12 to 18 inches. The sheer size difference can pose challenges. For one, you would need a significantly large tank – think in the range of hundreds of gallons – to accommodate both fish comfortably.

Territory is another key concern. While Arowanas tend to occupy the upper regions of a tank, Oscars are more mid-to-bottom dwellers. This separation might seem to suggest that the two could coexist peacefully. However, Oscars can be territorial and may occasionally venture to the top, which could result in confrontations.

Moreover, other fish have strong predatory instincts. While they might not view each other as food, there’s no guarantee they won’t occasionally nip at one another, especially during feeding times or when establishing dominance. Such aggressive interactions could lead to injuries.

Lastly, water conditions need to be just right. Both species require clean, well-oxygenated water with efficient filtration. While their pH and temperature preferences align somewhat, achieving a balance that caters to both can be a challenge.

Can Arowana Be Kept Alone?

Arowanas, given their size and majestic appearance, can certainly be the centrepiece of any aquarium on their own. Many aquarists prefer to keep Arowanas solo, simply to avoid potential conflicts and to showcase their beauty without any distractions.

Another advantage of keeping Arowanas alone is that it becomes easier to manage their dietary and health requirements. These fish have specific needs, such as a varied diet that includes insects, smaller fish, and occasional fruit.

What Other Fish Can Arowana Live With?

If you’re keen on giving your Arowana some company, consider fish that are neither too small (to avoid becoming meals) nor too aggressive. Tank mates like Large Plecos, Clown Knifefish, or Giant Gouramis can be compatible given the right conditions. However, always observe their interactions and ensure the tank is spacious enough.

Can Oscar Be Kept Alone?

Oscars, with their lively personalities, can thrive when kept alone. This gives them ample space to grow and express their behaviors without the threat of territorial disputes. Given their interactive nature, they often form strong bonds with their owners, recognizing them and even responding to feeding cues.

What Other Fish Can Oscar Live With?

Oscars can coexist with other large, semi-aggressive fish. Common tank mates include Convict Cichlids, Jack Dempseys, or even large Catfish. As always, ensure the tank is spacious, and monitor for signs of aggression or stress.
