The Boeseman's Rainbowfish,Melanotaenia boesemani,is an active and good sized rainbow fish, reaching up to 4.5 inches (11.5 cm). Looking at a mature male makes it easy to see why they are called Bicolour Rainbow fish. It is a beautiful blue-grey on the front half of the body and a vibrant orange-red on the back half. The secret to good colours is to buy quality specimens, feed a varied diet, and above all keep up with frequent water changes and maintenance.
As with most rainbow fish, Boesemani Rainbowfish are excellent fish for beginners. They are hardy fish that are best kept in schools and so need a large aquarium, 150 gallons or more. They will light up your tank with their beauty. If breeding is something you wanted to try, the Boeseman's Rainbowfish is a great choice for that as well.
