Jardini Arowana vs. Silver Arowana: Which One Is Better for Your Home Aquarium?

Arowanas are among the most sought-after fish for large home aquariums, admired for their graceful swimming and striking appearance. But when choosing between a Jardini Arowana and a Silver Arowana, many aquarists wonder which one is the better fit. While both species share similarities, they differ in size, temperament, and care requirements.

If you're looking for a Jardini Arowana for sale, or trying to decide which Arowana species suits your setup, this guide will help you make the right choice.

Jardini Arowana vs. Silver Arowana: Key Differences

Before bringing one of these majestic fish home, it's essential to understand how they differ.

1. Size and Growth Rate

• Silver Arowana: Can grow up to 3 feet (36 inches) long, making them one of the largest freshwater aquarium fish. They require a massive tank (250+ gallons) as they mature.

• Jardini Arowana: Generally grows to about 2 feet (24 inches), making them slightly more manageable than the Silver Arowana. However, they still need a large tank (180+ gallons).

While Jardini Arowanas are smaller, they still require plenty of space to thrive. If you have limited room, neither species may be suitable.

2. Temperament and Aggression

• Silver Arowana: Known for being relatively peaceful compared to other Arowanas. However, they can still be territorial and may eat smaller tank mates.

• Jardini Arowana: Far more aggressive and territorial than Silver Arowanas. They often do not tolerate other fish in their tank and are best kept alone.

If you're looking for a fish that can potentially coexist with tank mates, a Silver Arowana is the better option. But if you want a striking, solitary predator, the Jardini Arowana might be more appealing.

3. Care Requirements

Both species require similar care, but there are a few differences:

• Tank Size: Silver Arowanas need a bigger tank due to their size. Jardinis can manage in a slightly smaller space, but they are still large fish.

• Diet: Both species are carnivorous and thrive on a diet of live food, frozen food, and high-protein pellets. Silver Arowanas tend to be less picky, while Jardini Arowanas may be more aggressive during feeding.

• Water Parameters: Both need warm, clean water (75–82°F) with a pH between 6.5 and 7.5. A strong filtration system is essential.

Which Arowana Is Better for Beginners?

If you're new to Arowanas, the Silver Arowana is usually the better choice. Here’s why:

• Less aggressive – More tolerant of other fish.

• Easier to care for – Less sensitive to minor water fluctuations.

• Readily available – Found in most aquarium shops.

On the other hand, Jardini Arowanas are better suited for experienced fish keepers because:

• Highly aggressive – Not ideal for community tanks.

• More territorial – Can be difficult to manage in a confined space.

• Expensive and less common – Harder to find compared to Silver Arowanas.

If you’re a beginner and determined to keep an Arowana, start with a Silver Arowana. If you have experience with predatory fish and want a bold, solitary species, the Jardini Arowana might be a better fit.

How to Choose the Right Arowana for Your Aquarium

Still unsure which one to get? Consider these factors:

Tank Size: If you can accommodate a huge tank (250+ gallons), a Silver Arowana might be a great option. If you have slightly less space (180+ gallons), a Jardini Arowana could work.

Experience Level: If you’re new to Arowanas, stick with a Silver Arowana. If you’re confident in handling aggressive, territorial fish, try a Jardini Arowana.

Tank Mates: If you want a community setup, a Silver Arowana is your best bet. If you’re okay with a single, dominant fish, then a Jardini Arowana is a solid choice.

Availability: Silver Arowanas are more common and easy to find. If you’re looking for something rarer and unique, a Jardini Arowana for sale might be harder to locate but worth the effort.

Final Thoughts: Which Arowana Is Best for You?

Both Jardini Arowanas and Silver Arowanas are stunning, powerful fish that require dedication and a large, well-maintained aquarium.

If you want a beautiful, manageable Arowana with a peaceful nature, go for a Silver Arowana. But if you prefer a smaller, more aggressive fish with a strong personality, a Jardini Arowana is the way to go.

No matter which one you choose, make sure you have the right setup, proper filtration, and a commitment to caring for these fascinating fish. Arowanas are not for beginners, but with the right knowledge, they can be a rewarding addition to any large home aquarium.
