Can An Arowana Live in a 55-gallon Tank? (Pros And Cons)

If you’re considering adding an Arowana to your aquatic family, one critical question likely crosses your mind: Is a 55-gallon tank sufficient for an Arowana? This is a common query, especially among enthusiasts eager to provide the best care for their fish.

Arowanas are renowned for their unique beauty and dynamic presence, making them a sought-after choice for aquarium enthusiasts. But, as with any fish, their health and happiness hinge on the environment we provide.

Thus, understanding the suitability of a 55-gallon tank for an Arowana is crucial for their well-being and to ensure they thrive in your care. In this article, we’ll explore various aspects of housing an Arowana in a 55-gallon tank.

Analyzing the 55-gallon Tank

It’s important to start with the basics when considering a 55-gallon tank for an Arowana. A standard 55-gallon tank typically measures around 48 inches in length, 13 inches in width, and 21 inches in height. This site offers a moderate amount of space for many aquarium fish, but let’s evaluate how it fares for an Arowana.

Pros of Housing an Arowana in a 55-Gallon Tank

1. Suitable for Young Arowanas: Initially, a 55-gallon tank can comfortably accommodate a juvenile Arowana, providing enough room for swimming and growth.
2. Easier Maintenance: Smaller tanks are often easier to clean and maintain, making them a convenient option for beginners or those with limited time.
3. Space Efficiency: For fish keepers with limited space, a 55-gallon tank is more manageable and fits easily in most homes.

Cons of Housing an Arowana in a 55-Gallon Tank

1. Limited Growth Space: As Arowanas grow rapidly, they will quickly outgrow a 55-gallon tank, leading to potential health issues due to cramped conditions.
2. Stress and Behavior Problems: Insufficient space can cause stress in Arowanas, leading to behavioral problems and a higher susceptibility to diseases.
3. Reduced Quality of Life: A restricted environment can hinder the natural behavior and swimming patterns of Arowanas, affecting their overall well-being and lifespan.
4. Frequent Upgrades Needed: As the Arowana grows, you’ll need to upgrade to a larger tank, which can be costly and challenging.

Challenges of a 55-gallon Tank for Arowanas

Housing an Arowana in a 55-gallon tank presents several challenges that are crucial to consider for the well-being of these majestic fish.

Space Limitations and Growth Potential

1. Inadequate Growth Space: Arowanas are fast-growing fish that can reach up to 3 feet in length. A 55-gallon tank, with its limited dimensions, restricts this natural growth, potentially leading to physical deformities and health complications.
2. Restricted Movement: Arowanas are active swimmers. In a confined space, they are unable to exhibit their natural swimming behavior, which is essential for their physical and mental health.

Water Quality and Maintenance Challenges

1. Rapid Water Quality Deterioration: Due to their size and diet, Arowanas produce a significant amount of waste. In a 55-gallon tank, the water can quickly become polluted, leading to harmful ammonia and nitrate levels unless meticulously maintained.
2. Increased Maintenance Requirements: To ensure a healthy environment, frequent water changes and filter maintenance are necessary. This can be demanding and time-consuming for the aquarium keeper.

Stress and Behavioral Issues Due to Confined Space

1. Stress-Induced Health Problems: Limited space can cause chronic stress in Arowanas, weakening their immune system and making them more susceptible to diseases.
2. Behavioral Changes: Stress from confinement often leads to behavioral issues such as aggression, lethargy, or abnormal swimming patterns, which are signs of an unhappy and unhealthy fish.

Alternatives and Recommendations

While a 55-gallon tank poses challenges for housing an Arowana, there are alternatives and recommendations that can help ensure the health and well-being of these beautiful fish.

Suggesting Larger Tank Sizes for Arowanas

1. Optimal Tank Size: Ideally, Arowanas should be kept in tanks that are at least 250 gallons. This size provides ample space for swimming and growth, essential for their long-term health.
2. Consider Tank Shape: Long and wide tanks are preferable over tall ones, as Arowanas need more horizontal space to swim. A tank with a larger surface area is also beneficial for better oxygenation.

Alternatives for Those with Space Limitations

1. Smaller Arowana Species: If space is a constraint, consider smaller Arowana species that don’t grow as large and can thrive in relatively smaller tanks.
2. Tank Sharing: Explore community tank options where Arowanas can coexist with other large fish. This requires careful planning to ensure compatibility and adequate space for all inhabitants.

Tips for Optimizing a 55-gallon Tank

1. Frequent Water Changes: To maintain water quality in a smaller tank, perform regular and more frequent water changes, ideally 20-30% weekly.
2. Effective Filtration System: Use a high-quality filtration system that can handle the high bioload of an Arowana, keeping the water clean and well-oxygenated.
3. Monitor Fish Growth: Keep a close eye on the Arowana’s growth. Once it begins to outgrow the 55-gallon tank, start planning for a larger habitat.
4. Enrichment and Decor: Provide adequate hiding places and tank decorations that do not restrict swimming space. This can help reduce stress in a confined environment.

In summary, while a 55-gallon tank is not ideal for an Arowana, understanding and implementing these recommendations can help mitigate some of the issues. However, for the long-term health and happiness of an Arowana, investing in a larger tank is the most effective solution.
