Arowana Fish Tank Mates: Who Can Live Together?

Arowana fish, with their distinctive appearance and regal demeanor, are truly the kings of the aquarium world. However, finding the Best Arowana Fish Tank Mates for these majestic creatures can be a daunting task. In this comprehensive guide, we’ll explore the best options for creating a harmonious aquatic community that complements the Arowana’s unique needs.

Solitary Splendor: Should Arowanas Be Kept Alone?

While arowanas can thrive in solitary environments, introducing compatible tank mates can enhance their overall well-being and provide a more dynamic ecosystem. It’s essential to carefully select species that won’t pose a threat or cause unnecessary stress to the arowana.

Arowanas are known for their massive size and territorial nature, so it’s crucial to provide ample space and hiding spots for both the arowana and its potential tank mates. A spacious aquarium tank is a must, and setting up the right environment can be a game-changer for a successful community aquarium.

7 Best Arowana Fish Tank Mates

1. Jaguar Cichlid – A large, aggressive cichlid that can hold its own against an arowana. Needs a minimum 75-gallon tank.
2. Silver Dollar Fish – A fast, mid-level swimmer that can help disperse an Arowana’s aggression. Avoid if they nip the Arowana’s fins.
3. Clown Loach – A peaceful bottom dweller that stays out of an Arowana’s way. Keep in groups of 6 or more in a large tank.
4. Firemouth Cichlid – A peaceful cichlid that spends time in the middle and bottom of the tank. Has similar water requirements as arowanas.
5. Ornate Bichir – A large, hardy fish that can survive an Arowana’s aggression. Needs an extra large tank of 1500+ gallons.
6. Redtail Catfish – A huge, territorial catfish that can be kept with arowanas in a massive tank. Reaches nearly human size.
7. Oscar Fish – An intelligent, trainable cichlid that is large enough to defend itself against an arowana. Produces a lot of waste so needs frequent cleaning

Peaceful Companions: Suitable Tank Mates for Arowanas

When selecting tank mates for arowanas, it’s crucial to consider their temperament, size, and dietary preferences. Here are some suitable options to explore:

Large Peaceful Fish

Robust and peaceful species like silver arowanas and golden arowanas can make excellent companions for arowanas. These fish are often compatible due to their similar size and calm nature.

Other potential options include larger cichlids like Oscars, green terrors, and jack dempseys, as well as sleeper gouramis and other large gouramis.

Mid-sized Community Fish

While arowanas may view smaller fish as potential prey, certain mid-sized species can coexist peacefully with them. Consider adding Malaysian red arowanas, clown knifefish, or larger barbs like tinfoil barbs or tiger barbs to your Arowana’s tank.

It’s important to provide ample hiding spots and break lines of sight to prevent potential aggression from the arowana towards these mid-sized tank mates.

Bottom Dwellers and Algae Crew

Arowanas appreciate a clean environment, and adding bottom-dwelling species like plecos and certain catfish can help maintain a tidy tank. Bristlenose plecos and clown plecos are excellent choices for their algae-eating abilities and peaceful nature.

Bottom-dwelling species like black diamond stingrays and larger suckermouth catfish can also make interesting additions, as they occupy different vertical spaces within the tank, reducing potential conflicts with the arowana.

Feeding Frenzy: Dietary Considerations

When introducing tank mates to an Arowana’s aquarium, it’s crucial to consider their dietary preferences. Arowanas are primarily carnivorous, and their tank mates should be able to thrive on a similar diet or coexist without competing for food.

Use high-quality fish food pellets or live foods to ensure that all inhabitants receive proper nutrition. It’s also essential to provide ample hiding spots and feeding areas to prevent potential bullying or food competition.

Tank Size Matters: Accommodating Arowana’s Growth

Arowanas are known for their impressive size, with some species reaching lengths of up to 3 feet or more. When selecting tank mates, it’s crucial to consider the adult size of the arowana and its potential companions.

A 170-gallon aquarium or larger is recommended for housing an adult arowana, with ample space for its tank mates to thrive. Overcrowding can lead to stress, aggression, and poor water quality, so it’s essential to provide a spacious environment for all inhabitants.

Incompatible Companions: Species to Avoid

While some fish species can coexist peacefully with arowanas, others should be avoided altogether. Aggressive or territorial cichlids, such as flower horns and red devils, can pose a significant threat to arowanas and should be kept separate.

Additionally, smaller fish like tetras, danios, and guppies may be viewed as prey by the arowana and should be avoided as potential tank mates.

Monitoring and Adjustments

Introducing the Best Arowana Fish Tank Mates to an Arowana aquarium is an ongoing process that requires careful observation and adjustments. Monitor the behavior of all inhabitants closely, and be prepared to make changes if necessary.

If aggression or stress becomes apparent, it may be necessary to remove or relocate certain tank mates to ensure the well-being of all inhabitants. Patience and a willingness to adapt are key when creating a harmonious aquatic community with arowanas.

By following these guidelines and considering the unique needs of arowanas and their potential tank mates, you can create a captivating and thriving aquatic ecosystem that showcases the beauty and majesty of these extraordinary fish.

Remember, proper research, preparation, and ongoing care are essential for maintaining a successful arowana community aquarium. Embrace the challenge and enjoy the rewarding experience of creating a stunning underwater world for these magnificent creatures.
