Melanotaenia Australis

Datasheet

General Description

The Western Rainbowfish, scientifically known as Melanotaenia Australis, is a species that showcases a wide range of colors and patterns, influenced by its locality in Australia. Typically, adult specimens are not commonly available for sale, with juvenile fish being more prevalent in the trade. Patience is essential, as it can take over a year for their full coloration to develop.

Aquarium Setup

For optimal thriving conditions, a planted aquarium is recommended for the Western Rainbowfish. Dense vegetation should be provided alongside open swimming spaces. Water movement can vary from slow to moderate, although it is suggested to keep it on the lower side as live plants generally prefer calmer waters.

Behaviour

Characterized as very peaceful, the Western Rainbowfish can be disruptive to slower or smaller fish due to its rapid movements and relatively larger size. Suitable tankmates include similarly-sized rainbowfish, characins, danios, barbs, freshwater gobies, and catfish like Corydoras.

Feeding and Diet

The Western Rainbowfish is an unassuming eater and will accept various dried, frozen, and live foods. Regular feedings of live foods are recommended to enhance their coloration and overall health.

Reproduction & Dimorphism

Breeding the Western Rainbowfish is not overly challenging, as they are egg scatterers. However, raising the fry can present difficulties. Sexual dimorphism is evident as mature males are larger and display more vibrant colors than females, with deeper bodies and longer dorsal and anal fins.

Habitat and Distribution

In their natural habitat in Australia, Western Rainbowfish can be found in a variety of locations such as swamps, lagoons, lakes, and rivers, with a preference for streams and tributaries. They often seek refuge under aquatic vegetation or submerged debris to shelter from seasonal changes in temperature, water levels, and sediment.
