The fish, up close
The Boesemani Rainbowfish, scientifically known as Melanotaenia boesemani, is a strikingly colourful freshwater fish found in the rivers of Papua New Guinea. This species is named after the Dutch ichthyologist Marinus Boeseman and is highly sought after by aquarists for its vibrant hues and peaceful demeanor. Boesemani Rainbowfish display an iridescent blue body that transitions into a vivid orange to red colouration along its midsection. Their fins are accentuated with yellow and black markings, adding to their overall beauty. These active swimmers thrive in well-planted aquariums with ample swimming space and peaceful tankmates.
Care guide
Use these notes to shape a setup around the fish, then speak with our team about the tank you have in mind.
Plan your setupBehaviour
Boesemani Rainbowfish are known for their peaceful and social nature, making them excellent community tank inhabitants. They are schooling fish that should ideally be kept in groups of at least six individuals to feel secure and display their best colours. These fish are active swimmers and appreciate open areas for swimming, as well as densely planted areas for hiding and breeding.
Tank planning
Maintaining stable water parameters is crucial for the health of Boesemani Rainbowfish. They prefer slightly acidic to neutral water with a temperature range of 24-28°C and a pH level between 6.5-7.5. Regular water changes and adequate filtration are essential to keep their environment clean and healthy. Provide ample hiding spots and plants for them to feel secure, and ensure they have enough space to swim freely.
