One of the most popular Rainbowfish in the aquarium hobby, the Boeseman’s Rainbowfish are known for their bright coloration. These fish are native to Indonesia and can be found in only a single area called Ajumaru which contains three lakes. Adult Boeseman’s Rainbowfish exhibit a brilliant orange color on the back half of their bodies, while the front half is usually blue-gray. The body may also exhibit a series of narrow, dark-colored bars. Males of the species tend to be more colorful than females and full coloration may take up to 12 months to fully develop. The juvenile specimens seen in dealers tanks are very drab and, for this reason, may often be overlooked by the inexperienced aquarist. These fish truly are a diamond in the rough!
