The Parkinsoni Rainbowfish (Melanotaenia parkinsoni) is a spectacular large rainbowfish celebrated for its shimmering metallic blue body, vivid orange to red fins and impressive adult size. Native to the fast-flowing rivers and streams of northern Papua New Guinea, this active and peaceful species is highly prized by aquarists seeking a colourful centrepiece for larger freshwater aquariums.
As a true schooling fish, Parkinsoni Rainbowfish thrive when kept in groups of six or more. Males develop the most intense colours when displaying to females and competing with other males, creating an incredible display of flashing blues and fiery orange fins. Their energetic swimming behaviour makes them a standout feature in spacious planted aquariums and large community tanks.
This hardy species prefers a well-maintained aquarium with open swimming areas, dense planting around the edges and excellent water circulation. They eagerly accept high-quality flakes, pellets, frozen foods and live foods, with a varied diet helping to maximise their vibrant colouration and overall health.
With their striking appearance, peaceful temperament and constant activity, the Parkinsoni Rainbowfish is an exceptional addition to any large freshwater community aquarium.

Large planted aquariums, peaceful community aquariums and rainbowfish displays
Yes. They are hardy and relatively easy to care for, provided they are housed in a suitably large aquarium with stable water conditions.
They should be kept in schools of at least six fish. Larger groups encourage natural schooling behaviour and allow males to display their most vibrant colours.
They are omnivores and thrive on a varied diet of premium flakes, pellets, frozen foods such as bloodworms and brine shrimp, along with occasional live foods.
Absolutely. They are peaceful and do well with other similarly sized community fish, including larger tetras, Corydoras, peaceful barbs and other rainbowfish.
Yes. They flourish in planted aquariums with dense vegetation around the perimeter and plenty of open swimming space through the centre.
Yes. Like most rainbowfish, they readily scatter adhesive eggs among fine-leaved plants or spawning mops. Removing the eggs from the adults significantly improves fry survival.
Parkinsoni Rainbowfish are schooling fish and should always be kept in groups. Small groups often lead to stress and reduced colouration.
These large, active swimmers require plenty of open space. A spacious aquarium is essential for their health and natural behaviour.
While they readily accept prepared foods, adding frozen and live foods helps enhance colour, health and breeding condition.
Consistent water changes and excellent filtration are important for maintaining their vibrant colours and long-term wellbeing.
Avoid aggressive or fin-nipping species that may harass these peaceful rainbowfish and cause unnecessary stress.
Provide a balance of dense planting and open swimming areas to allow the school to move freely and display naturally.
