Boeseman's Rainbowfish Melanotaenia boesemani , also known as the Boesemani Rainbowfish.
The Boesemani Rainbow creates a colorful centerpiece for any freshwater home aquarium. Males have a beautiful bluish purple head that fades into a gorgeous orange and yellow posterior. Though females are not as colorful, their brilliant silver coloration is equally as stunning against any backdrop of plants or rockwork. Regardless of sex, however, Melanotaenia boesemani boasts the same distinct characteristics as other Rainbowfish, including large eyes, a deeply forked mouth, and dual dorsal fins. Like many members of the Melanotaeniidae family, the Boesemani Rainbow also boasts the characteristic blackish-silver band of scales running laterally from gill to tail.
