6 Ideal Tank Mates to Pair With Arowanas

In aquariums, Arowanas stands out as the majestic rulers of the waters. Their striking appearance and graceful movements make them a sought-after addition to any tank. However, the key to a thriving aquatic community lies in choosing suitable tank mates for your Arowana. To ensure a harmonious environment, we’ve compiled a comprehensive list of ideal companions for your Arowana. Let’s explore each one in detail!

1. Silver Dollars

One of the critical reasons why Silver Dollars are popular in the aquarium hobby is their compatibility with a wide range of fish species. They are known to be excellent tank mates for other peaceful fish, including tetras, angelfish, and Arowanas. Their gentle disposition and striking appearance make them appealing for community aquariums.

Silver Dollars are the social butterflies of the aquatic world. Their dazzling silvery scales and round, disk-like bodies create a captivating contrast to the Arowana’s elegance. These peaceful herbivores not only add aesthetic appeal but also bring a sense of tranquility to your tank. Their easy-going nature makes them the ideal tank mates for Arowanas, ensuring a harmonious coexistence.

2. Bichir Fish 

Bichirs are generally peaceful fish, but they are also predators. They may eat smaller fish that can fit in their mouth, so choosing tank mates is essential. Fish of a similar size and temperament, such as other Bichirs or non-aggressive species, make suitable companions. They are a good choice for tanks with larger, calm fish like Arowanas, as they won’t outcompete or intimidate these majestic fish.

Bichir fish may look like prehistoric relics, and that’s part of their charm. Their rugged appearance, elongated bodies, and tough scales provide a unique juxtaposition to the Arowana’s regal presence. Bichirs are generally slow-moving and non-aggressive, making them the perfect companions for Arowanas, as they won’t outpace or intimidate your prized fish.

3. Black Ghost Knifefish

For mystery and intrigue in your aquarium, consider adding Black Ghost Knifefish. With their sleek, dark bodies and undulating movements, they are sure to capture your attention. These nocturnal creatures remain inactive during the day, ensuring they won’t disrupt your Arowana’s daily activities. They coexist well with Arowanas, as they are nocturnal and won’t interfere with the daily activities of these magnificent fish.

4. Clown Loaches 

Clown Loaches are the way to go to inject vibrant energy into your tank. Their colorful appearance, playful behavior, and distinctive markings add a lively dimension to your aquarium. Known for their friendly and peaceful nature, Clown Loaches make great companions for Arowanas, enhancing the overall visual appeal of your tank. Just ensure that they have plenty of space to swim and explore.

5. Plecos

Plecos, short for “Plecostomus,” is a common name for various catfish species in the Loricariidae family. They are known for their distinctive appearance, characterized by a flattened, armored body covered in bony plates and a suction-cup mouth. These fish come in various colors and patterns, with some species displaying spots or stripes. Depending on the species, Plecos can vary from small, around 3 inches (8 centimeters), to much larger, exceeding 2 feet (60 centimeters).

Plecos are the unsung heroes of aquarium maintenance. Their primary role is to keep your tank clean, as they are excellent bottom feeders. Their armored bodies protect them from a potential curiosity of your Arowana, and their diligent scavenging ensures your tank remains in pristine condition. Arowanas and Plecos can coexist peacefully while maintaining an organized and hygienic environment.

6. Tinfoil Barbs

Tinfoil Barbs (Barbonymus schwanenfeldii), often called Tinfoil Fish or Tinfoil Barbfish, are popular freshwater fish known for their striking, silvery appearance. These fish get their name from the shiny, reflective scales that resemble tinfoil. They have elongated bodies and can grow quite large, reaching lengths of up to 14 inches (35 centimeters) or more in the right conditions. A distinctive red or orange fin often highlights their scales.

Tinfoil Barbs are generally peaceful fish and make great tank mates for other temperate species. They coexist well with community fish like tetras, barbs, and angelfish. They are also ideal for larger and active fish like Arowanas, as they can keep up with the Arowana’s active swimming and add a vibrant element to the tank. These fast swimmers can keep up with the dynamic nature of Arowanas, ensuring that both species coexist without any stress or conflict.

Pairing suitable tank mates with your Arowana is not just about aesthetics; it’s about creating a balanced and serene underwater world. The carefully selected fish listed here are known to coexist harmoniously with Arowanas, making your aquarium a captivating, tranquil, and flourishing habitat. Choose your Arowana’s companions thoughtfully, and watch your aquatic realm come to life with beauty and serenity!
