Melanotaenia boesemani

Boeseman's rainbowfish is one of the most colorful of this family, and another which prefers hard water. Breeding is straightforward, though the fry accept only tiny prey. Another gorgeously colored species, M. herbertaxelrodi (Lake Tebera rainbowfish), is sometimes available commercially. Size: 10-12 cm.
