60x Boesemani Rainbow 4-5cm

60x Local Rainbow Bosemani

Rainbowfish are one of the most iconic groups in the freshwater aquarium hobby, and no species exemplifies their striking beauty quite like the Boesemani Rainbowfish. Originally found in the Ayamaru Lakes region of West Papua, this species has captured the hearts of aquarists worldwide with its electric two-tone colouration. Thanks to dedicated local breeders, this listing offers locally bred stock, which means the fish are hardier, better acclimated, and often more vibrant than imported counterparts.

Boesemani Rainbows feature the classic rainbowfish body shape, being streamlined, deep-bodied, and built for constant motion. What makes them especially unique is the dramatic split in colouration from front to back, with a deep iridescent blue covering the head and shoulders, which blends seamlessly into vivid orange, red, or yellow tones toward the tail. Males tend to show stronger colour contrast, especially as they mature and during spawning displays, while females remain more muted but equally graceful.

Breeding these Rainbowfish in captivity is a rewarding experience as they will readily spawn in well-maintained aquariums. A typical breeding setup includes slightly softer and more acidic water conditions than their regular tank, with fine-leaved plants or spawning mops for the females to deposit their eggs. Post-spawning, parents may need to be removed to prevent egg predation, and the fry can be raised on a diet of infusoria or finely crushed flake food until they are large enough to accept larger feed.

Tank Recommendations for your 60x Local Rainbow Bosemani

Boesemani rainbows are medium to large growing rainbowfish that reach up to 12 cm in length, and they are incredibly active swimmers. A school of 60 individuals will need a minimum tank volume of 600 litres, although larger systems will always be appreciated, especially if you plan to include other species.

These fish thrive in heavily planted aquariums with plenty of open space for swimming. Boesemani's prefer to occupy the upper and mid-levels of the water column, and their brilliant colours are best showcased against a backdrop of lush greenery or dark substrate. A sand or fine gravel base is ideal, and a tight-fitting lid is essential as rainbowfish are skilled jumpers. These locally bred fish are best kept at 24-28°C for peak colouration and vitality.

Suitable Tank Buddies

The Bosemani rainbowfish is incredibly peaceful, but due to their speed and active nature, they may outcompete slower or bottom-dwelling tank mates during feeding. They can, however, be kept in a wide range of community aquarium settings and with other rainbowfish species.

Usually Compatible

Other rainbow fish species, a range of tetra species such as lemon tetras, black widow tetras, and Congo tetras, along with danio species as well.

Sometimes Compatible

Corydoras, Apistogramma, angelfish, and other smaller or potentially slow-moving species.

Rarely Compatible

Aggressive species that may prey on the Bosemani rainbowfish. Any incredibly small species, such as shrimp, should be avoided, as they may be eaten by the rainbow fish.

Feeding your 60x Local Rainbow Bosemani

Bosemani rainbowfish will take aquarium foods very easily. They will take a wide range of pellets, flakes, and frozen foods. By giving them a varied diet, it ensures that they have optimal nutrition. The ideal diet would be a good quality floating food, supplemented with frozen bloodworms or black worms, or even live foods like baby brine shrimp. Feeding any foods with natural colour enhancers would also be great, as this will really enhance the stunning hues.
