Melanotaenia Trifasciata

Datasheet

General Description

M. trifasciata, commonly known as the Banded Rainbowfish, displays a diverse array of colors and patterns depending on its origin. Adherence to keeping morphs separate in aquariums is crucial to prevent hybridization. Juveniles are predominantly available in the market, with adult specimens rarely seen until substantial color development occurs over a year.

Aquarium Setup

The Banded Rainbowfish thrives in a planted tank with dense vegetation and some open swimming spaces. Water movement should be slow to moderate while maintaining a pH range of 6.5-8.0, hardness of 8-20\xC2\xBAdH, and a temperature between 24-33\xC2\xBAC. Detailed setup requirements can be referred to from the provided table.

Behaviour

Generally peaceful, the Banded Rainbowfish can be disruptive to smaller or slower fish due to its swift movements and relatively large size. Suitable tankmates include similarly-sized rainbowfish, characins, danios, barbs, freshwater gobies, and catfish like Corydoras.

Feeding and Diet

This species has an adaptable diet, accepting various dried, frozen, and live foods. Color vibrancy is enhanced with regular consumption of live foods, ensuring optimal health and appearance.

Reproduction & Dimorphism

Breeding the Banded Rainbowfish is relatively uncomplicated, with the species being egg scatterers. Adult males are larger with brighter colors, deeper bodies, and longer dorsal and anal fins compared to females. However, populations from specific Australian rivers may not display this typical dimorphism.

Habitat and Distribution

Found predominantly in Australia, the Banded Rainbowfish prefers slightly alkaline waters and inhabits a range of environments, including swamps, lagoons, lakes, rivers, and flowing streams and tributaries. These biotopes often experience seasonal fluctuations in temperature, water levels, and sediment content. The fish seek shelter under aquatic vegetation or debris like submerged logs.
