Melanotaenia affinis, the New Guinea rainbow fish, is found in north Papua New Guinea. Of the three known varieties, the so-called standard variety has the widest range. It is commonly found in the Markham, Ramu, and Sepik Rivers; their preferred habitat includes clear rainforest streams, swamps, pools, and lagoons abundant in vegetation and submerged logs.

The New guinea rainbowfish is a peaceful and adaptable rainbowfish species that grows to 14 cm. It favors a pH of 7.0, hard water: (100–150 mg/l) and a temperature of 21-28 C (70 to 82 F) . It will eat small live foods and prepared diets. Just like related species, it should be kept in shoals.
