Parkinsoni Rainbowfish (Melanotaenia parkinsoni) for Sale

The Parkinsoni Rainbowfish (Melanotaenia parkinsoni) is one of the most rewarding rainbowfish in the freshwater hobby. Hailing from the clear coastal streams of southeastern Papua New Guinea, mature males develop a striking two‑tone look—a silvery blue‑grey front half that gives way to vivid yellow and orange flanks and fins. Peaceful, active, and endlessly social, this hardy schooling fish brings constant movement and brilliant color to a planted community aquarium and is an excellent choice for both newer keepers and seasoned aquascapers.

Like our other rainbowfish, Parkinsoni look their absolute best when kept in a group, where the males display intensified color as they show off to one another and to the females.
