Melanotaenia boesemani Red

A Little More Information...

Melanotaenia boesemani Red is a red form of Boeseman’s famous rainbowfish, originating from Indonesia and associated with Aves Creek. Its warm coloration, contrasting with the blue or green shades of the classic form, makes it highly valued by aquarists. Like other rainbowfish, it thrives in a group, in clean, well-oxygenated and stable water. This variety remains less common than the usual commercial strains. A spacious aquarium, efficient filtration, varied food and peaceful tank mates help display its schooling behaviour and colours, which are especially vivid in mature males.

General species description

Melanotaenia boesemani Red belongs to the rainbowfish of New Guinea. It is a red form of Melanotaenia boesemani, not a separate species. Its laterally compressed body and well-developed fins match the typical profile of Melanotaeniidae. Active during the day, it should be kept in a group of at least six fish to encourage natural behaviour and reduce nervousness. Adult males often display to one another, especially when in good condition. The Red form is less common in the trade than the classic form, making stable water quality and a reliable source particularly important.

Geographical origin and habitat

This form is associated with Aves Creek in Indonesia, in the western New Guinea region. It inhabits freshwater streams where the water is generally clear, warm and well oxygenated. The habitat includes shallow areas, calmer margins and riparian vegetation that can provide shade and shelter. In an aquarium, stable water, moderate circulation and good oxygenation reproduce these conditions more effectively than a strong current. A temperature of 24 to 28 °C and slightly neutral to alkaline pH are suitable for long-term care.

Precise location and local name

The geographic name associated with this form is Aves Creek. In the aquarium trade, it is generally called Aves Creek Rainbowfish or Melanotaenia boesemani Red. The most useful local designation for identification is therefore Aves Creek. This name distinguishes it from other geographic populations or colour selections of Melanotaenia boesemani. To preserve the value of the strain, it is best not to mix it with other geographic or commercial forms when maintaining a defined origin and colour pattern is important.

Appearance and physical characteristics

The body is deep, laterally compressed and covered with small, shiny scales. In this form, the dominant colour tends toward orange-red to copper-red, especially across the rear half of the body and in displaying males. The head may show darker or bluish shades, while the fins are often red, orange or translucent. Mature males are generally larger and more intensely coloured than females. The commonly accepted maximum size for the species is about 10 cm, with variation related to sex, diet and rearing conditions.

General diet

Melanotaenia boesemani Red is an opportunistic omnivore that readily accepts commercial foods. A base of quality pellets for tropical fish can be supplemented with small frozen or live foods such as mosquito larvae, brine shrimp and daphnia. Small portions offered once or twice daily suit adults, while excess food should be avoided because it can impair water quality. A varied diet supports growth, vitality and colour intensity. Juveniles benefit from finer particles and frequent feeding, adjusted to their small mouths.

In your aquarium

To succeed with Melanotaenia boesemani Red, provide a long, tightly covered aquarium because this active fish may jump. Keep it in a group, leave open swimming areas and use filtration that creates steady circulation without excessive current. Clean water, consistent water changes and a varied diet are essential. Since the Red form is less common, avoid mixing it with other strains if you want to preserve its colour and identity. Peaceful companions, moderate lighting and plants around the margins complete a balanced setup.
