Can 2 Arowana Live Together

No, two Arowana should not live together. These fish are naturally aggressive and territorial in nature, and when kept in the same tank, they will fight for dominance. As a result, one of the fish could end up seriously injured or worse.

Keeping them only in pairs is also not recommended as this can put too much stress on the pair to breed, resulting in aggression towards each other. It is generally better to keep one Arowana per tank with plenty of hiding spots and decorations so that it feels secure and has enough space to establish its own territory without having to compete with another Arowana. In the realm of ornamental fishkeeping, few species command as much respect and awe as the majestic Arowana. Known for their distinctive appearance and graceful movements, Arowanas have captivated the hearts of aquarium enthusiasts around the world. As passionate hobbyists delve deeper into the world of these mesmerizing creatures, a common question arises: can two Arowanas coexist harmoniously in the same aquarium? Let’s dive into the fascinating realm of Arowana behavior and social dynamics to unravel the answer.

How Many Arowana Can Be Kept Together?

Arowana is solitary fish that should not be kept together, as they can become territorial and aggressive in close quarters. However, if the tank is large enough, some hobbyists have had success keeping 2–3 Arowana of the same species together in a single tank. It’s important to remember that each additional Arowana will require more space, so it’s best to start with only two or three and then gradually increase the population.

Additionally, any other fish added to the tank must be chosen carefully – smaller fish may be seen as potential prey by an Arowana and larger fish may pose competition for food or territory.

Understanding Arowana Species:

To address the question of whether two Arowanas can live together, it’s crucial to understand the different species within the Arowana family. The most popular types are the Asian Arowana (Scleropages formosus) and the South American Arowana (Osteoglossum bicirrhosum). Both species boast stunning coloration and intricate patterns, making them highly sought after in the aquarium trade. However, it’s important to note that these two species should never be housed together due to their distinct habitat requirements and behavioral differences.

Can We Keep 2 Arowanas Together?

The answer to this question depends on the size of the tank they will be kept in. Generally, it is not recommended to keep two arowanas together in anything less than a 75-gallon aquarium. Arowanas are solitary fish and prefer their own space, so keeping them together can cause stress and altercations between them due to territorial disputes.

If you choose to house two arowanas together, make sure there is plenty of room for both of them and provide ample hiding spots for when disputes arise. Additionally, pay close attention to the water parameters as changes or fluctuations could also lead to aggression from one fish towards another.

Establishing Hierarchy:

In cases where Arowanas are kept together, a hierarchy often forms within the group. This social structure helps minimize conflicts and maintain a semblance of peace. When introducing multiple Arowanas, it’s essential to carefully observe their interactions. Subtle displays of dominance and submission are natural as they establish their pecking order. Providing ample hiding spots, driftwood, and plants can alleviate tension by offering retreats for subordinate individuals.

Can Arowana Be Together?

Yes, arowanas can be kept together in the same tank. However, it is important to note that arowanas are large and territorial fish, so they should only be housed with other compatible species of similar size. When introducing multiple arowanas into the same aquarium, it is very important to make sure the tank has enough space for them all to swim freely without feeling crowded or stressed out by one another’s presence.

Additionally, it is best practice to add new fish slowly over time rather than all at once, as this will help reduce aggression among existing specimens as well as any newcomers.

Environmental Enrichment:

Creating a stimulating environment is key to reducing stress and aggression among Arowanas. Enrichment activities such as introducing live plants, floating logs, and strategically placed decorations can provide mental stimulation and territorial boundaries. A well-structured aquarium mimicking their natural habitat can promote a sense of security, encouraging more peaceful cohabitation.

Are Arowanas Solitary?

Arowanas are not generally considered to be solitary fish. They prefer to live in schools or groups of at least three arowanas, although some have successfully kept single specimens. When they do form schools, arowanas will establish dominance hierarchies and defend their territories within the group.

Arowana should always be provided with enough room for them to swim freely since they can grow quite large and need plenty of space for comfortable social interaction. Additionally, it is important to feed them properly so that all members of the school get their share of food without competition from other members in the tank.
