The Boesemani Rainbowfish (Melanotaenia boesemani) is one of the most iconic and colourful freshwater fish in the aquarium hobby. Instantly recognisable by its striking half-blue, half-orange body, this spectacular species is native to the lakes of West Papua, Indonesia, and is highly prized for its vibrant colours, peaceful temperament and active schooling behaviour.
Boesemani Rainbowfish thrive when kept in schools of six or more, where males display their brightest colours while competing for attention. Their constant movement and shimmering colours make them a stunning centrepiece in larger planted aquariums and peaceful community tanks.
A spacious aquarium with open swimming areas, dense planting around the edges and high-quality filtration provides the ideal environment. These hardy omnivores readily accept premium flakes, pellets, frozen foods and live foods, with a varied diet helping to enhance their brilliant colouration.
Suitable for both beginner and experienced aquarists, the Boesemani Rainbowfish is an outstanding choice for anyone wanting a vibrant, energetic and peaceful schooling fish that brings life and colour to any freshwater aquarium.

Yes. They are hardy, adaptable and relatively easy to care for, provided they are kept in a spacious aquarium with stable water quality and regular maintenance.

Yes. They thrive in planted aquariums with open swimming areas and dense planting around the edges, allowing them to school freely while feeling secure.
Yes. Given excellent water quality and a nutritious diet, they readily spawn among fine-leaved plants or spawning mops. Eggs should be separated from adults to maximise fry survival.
Boesemani Rainbowfish are schooling fish and should always be kept in groups. Small numbers can result in stress, timid behaviour and dull colouration.
These active fish require long aquariums with plenty of open water to swim comfortably. Cramped tanks can reduce activity and overall health.
Although they readily accept dry foods, supplementing with frozen and live foods enhances colour, health and breeding condition.
Avoid housing them with aggressive or fin-nipping fish that may stress the school and damage their fins.
Stable water parameters and regular water changes are essential to maintain vibrant colours and prevent disease.
A mixed-sex group encourages natural display behaviour, with males showing their most intense colours when competing for females.
