Behavioral Insights of Jardini Arowana

Natural Behavior

In their natural environment, Jardini Arowanas exhibit fascinating behaviors. They are predatory by nature, often seen hunting near the water's surface, using their powerful jaws to capture prey. Although solitary, they may display territorial aggression towards intruders, especially during breeding seasons.

Aquarium Behavior

In captivity, Jardini Arowanas retain many of their wild behaviors. They are intelligent and observant, often recognizing their owners. However, their territorial nature calls for careful tank planning to prevent aggression towards tank mates.

Behavioral Considerations:
