Jardini arowana




Jardini arowana

The Jardini arowana native to both Australia and South Central New Guinea is one of two species of arowanas that come from this region. Their body is covered in copper colored scales accented with small pink edges, which sometimes appear as pink spots on the fins. Similar to its silver sibling, the Australian arowana has the potential to grow to almost 3 feet in length.

Most consider the Australian arowana to be the “bad boy” of the arowana world due to their tendency to wear leather jackets and drive fast motorcycles fiery temperament. Because of this, keeping Aussie arowanas in a tank with others can be a real challenge. While some have certainly succeeded in keeping them in communities, most Australian arowanas won’t tolerate tank mates once they reach 12-14 inches in size.

Feeding and Nutrition of Jardini arowana

Jardini Arowana are carnivores and should be provided with a variety of meaty and vitamin enriched foods such as live, frozen or freeze-dried ghost shrimp, krill, minnows, bloodworms, blackworms, mealworms, earthworms, crickets, frogs, crayfish, and Cichlid/Arowana pellets or sticks.

Breeding Information

Jardini Arowana are mouth brooding, egg-layers and aquarium breeding is extremely difficult, but not impossible (a large tank of 600+ gallons would be needed). In the wild, spawning commences at the start of the wet season, where they will pair off and lay their eggs (50-200). Once fertilized, the female will keep the eggs in her mouth until they hatch.
When the fry hatch they will stay with their mother for around 4-5 weeks and threatened the mother will open her mouth allowing the young to seek shelter.

Aquarium Care

Jardini Arowana require an aquarium of at least 180 gallons with a sand or gravel substrate and should also be provided with driftwood and vegetation; it’s a good idea to have some free-floating plants or plants that will adhere to driftwood as some individuals do not tolerate rooted vegetation.
They will also require a secure, enclosed top on their aquarium as they are powerful and notorious jumpers. Weekly 15-25% water changes should be carried out (frequency can vary depending on aquarium filtration efficiency) as Jardini Arowana are very sensitive to water chemistry.
Jardini Arowana are a solitary, aggressive, territorial species, but have, on occasion, been known to coexist with large Oscars, large Manguense, large, predatory catfish, and large plecos, but it’s hit or miss and more often than not, they are eventually the only fish left in the aquarium.
