General information

The Jardini Arowana (Scleropages formosus) is a freshwater fish species that belongs to the family Osteoglossidae. It is also known as the Australian Arowana or Northern Arowana. This fish is native to the rivers and streams of Australia, Papua New Guinea, and parts of Southeast Asia. 
Jardini Arowanas are a popular ornamental fish species in the aquarium trade, known for their distinctive appearance and active swimming behavior. 
Jardini Arowanas can grow up to 90 cm (35 inches) in length, with males generally larger than females. They have elongated, streamlined bodies with large scales and a silvery or greenish coloration. The head is pointed and features a distinctive "tongue" that can be extended to catch prey. Jardini Arowanas also have a pair of long, feathery barbels under their chin.

In the wild, Jardini Arowanas are carnivorous and feed on a variety of prey, including fish, insects, crustaceans, and small mammals. In captivity, they can be fed a diet of live, frozen, or pellet food. It is recommended to offer a varied diet to ensure all nutritional needs are met.

It can be difficult to determine the sex of Jardini Arowanas, as there are no external differences between males and females. However, males are generally larger and more colorful than females.

Jardini Arowanas are known to breed in captivity, although it can be challenging to induce spawning. Breeding typically occurs in pairs or small groups, with males courting females by displaying their fins and performing elaborate dances. Females will lay eggs on the substrate or on plant leaves, which the male will fertilize.

Jardini Arowanas are generally hardy fish and not susceptible to many diseases if kept in good water conditions. However, they can be prone to bacterial infections, parasitic infestations, and fungal infections. Monitoring water quality and performing regular water changes to prevent disease is important.

Jardini Arowanas are native to the freshwater rivers and streams of northern Australia, Papua New Guinea, and parts of Southeast Asia.

Jardini Arowanas are known to be jumpers and can easily jump out of an aquarium if not properly covered. They also require a large tank and can become aggressive towards other fish species, so providing adequate space and tankmates is important.

Jardini Arowanas can be sensitive to water conditions and require careful acclimation when introduced to a new tank. It is recommended to slowly introduce the fish to the new water by floating the bag in the tank for at least 20 minutes and adding small amounts of tank water to the bag over time.
