Origins of the Arowana Scleropages Jardini

These fish are indigenous to the Adelaide and Jardine Rivers in Northern Australia, where they live in varied habitats from fast-flowing streams to still billabongs. The species is also found widely distributed across Oceana and in Central and South New Guinea. The Arowana is a powerful predatory fish whose origins can be traced back to prehistoric times, earning them the name “living fossil.” Wild Arowanas can grow to be up to 40 inches in length and are formidable predators, inhabiting the top to the middle areas of the tropical waters in which they live. Indigenous people often catch and eat the Silver Arowana.

Thanks to their unique hunting technique of hiding, stalking, and leaping right out of the water to grab small animals and insects from overhanging or nearby vegetation, these fish are nicknamed “water monkeys.”

Water conditions

The Scleropages Jardini is very sensitive to water quality and chemistry, preferring water with a pH between 6.0 and 7.0 and KH of between 2 and 4. The water temperature should be between 76⁰ and 85⁰ Fahrenheit. You’ll need to carry out 15% to 25% water changes every week or so, depending on the efficiency of your filtration system.
