Behaviour and Temperament
Aggression
Arowana fish are known for their aggressive nature. They have a reputation for being territorial and can become aggressive towards other fish, especially when they feel threatened or when they are defending their territory. They have a strong jaw and sharp teeth, which they use to catch and eat their prey.
When it comes to living with goldfish, it is important to note that goldfish are generally docile and peaceful. However, they can be quite active and playful, which can sometimes cause them to accidentally bump into other fish. This can trigger the Arowana’s aggressive behaviour, leading to potential conflicts.
Territorial Nature
Arowana fish are also territorial and can become quite possessive of their space. They require a lot of swimming room and prefer to have a large tank to themselves. If they feel cramped or confined, they may become stressed and aggressive towards other fish in the tank.
Goldfish, on the other hand, are more adaptable and can thrive in smaller tanks. They are not as territorial as Arowana fish and can coexist peacefully with other fish, as long as there is enough space for everyone.
In conclusion, while Arowana fish can be aggressive and territorial, goldfish are generally docile and peaceful. It is possible for them to live together in the same tank, but it is important to provide enough space for both species to thrive.
Compatibility with Other Species
When it comes to keeping Arowanas with other fish species, it’s important to consider compatibility. Arowanas are large and aggressive fish, so not all species will be suitable tank mates. In this section, we will discuss the compatibility of Arowanas with goldfish and other fish species.
Compatibility with Goldfish
Goldfish and Arowanas have different requirements when it comes to water temperature, pH levels, and tank size. Goldfish prefer cooler water temperatures between 65-72°F, while Arowanas thrive in warmer water temperatures between 75-82°F. Additionally, goldfish produce a lot of waste, which can lead to poor water quality if not properly maintained.
While it is technically possible to keep goldfish and Arowanas together, it is not recommended. The two species have different lifestyles and may not get along well in the same tank. Goldfish are peaceful and slow-moving, while Arowanas are active and aggressive. The Arowana may see the goldfish as prey and attack them.
Compatibility with Other Fish
When choosing tank mates for Arowanas, it’s essential to select species that can hold their own against these assertive swimmers. Ideally, you should avoid overly aggressive species that may stress out your Arowana. Some suitable tank mates for Arowanas include Oscars, Silver Dollars, Freshwater Stingrays, and Koi.
Clown Loaches are also a popular choice as they can help keep the tank clean by eating leftover food and debris. However, they may not be suitable for all Arowanas, as they can be quite active and may stress out more timid fish.
It’s important to note that Arowanas can be territorial and may attack other fish if they feel threatened. Therefore, it’s essential to provide plenty of hiding spots and space for each fish to establish its territory.
In conclusion, when considering tank mates for Arowanas, it’s crucial to choose species that are compatible with their aggressive nature and large size. Goldfish are not recommended as tank mates for Arowanas, while suitable tank mates include Oscars, Silver Dollars, Freshwater Stingrays, and Koi, among others.
