Boeseman's Rainbowfish Guide
The Boeseman's Rainbowfish (Melanotaenia boesemani) is a freshwater fish that truly stands out. The male fish is especially striking: the front half of its body is a shimmering blue or purple, while the back half glows orange or red. It is quite popular among aquarium hobbyists thanks to its bright colors and its lively, active nature. It’s unique because the bicolored body is rarely seen in other rainbowfish species.

Frequently Asked Questions
How many Boeseman's Rainbowfish should be kept together?
Since they are schooling fish, Boeseman's Rainbowfish should only be kept in groups of six or more. Keeping them in larger groups not only enhances their natural behavior but also reduces stress and aggression within the school.
What should I feed Boeseman's Rainbowfish?
Boeseman's Rainbowfish are omnivores and require a varied diet. For added variety and vital nutrients, they can occasionally be fed live or frozen delicacies like brine shrimp, bloodworms, or daphnia in addition to their regular diet of premium flakes or pellets.
What size tank do Boeseman's Rainbowfish need?
An expansive aquarium with lots of swimming space is ideal for the growth of Boeseman's Rainbowfish. A small school of these fish should fit nicely in a tank that is at least 50 liters in size.
