About
Boeseman's rainbowfish (Melanotaenia boesemani) is a medium-sized rainbowfish endemic to a very limited range of lakes in the Ayamaru region of West Papua (Irian Jaya), Indonesia, including Lakes Ayamaru, Aitinjo, and Hain. Growing to 8–12 cm, it is arguably the most dramatically colored of all rainbowfishes: the front half of the body is vivid blue-purple to indigo, while the rear half transitions abruptly into brilliant orange to yellow — a bicolor pattern of striking intensity. Males display richer coloration and deeper body profiles. Slightly alkaline, moderately hard water (pH 7.0–8.0) at 24–28°C is recommended. An active open-water swimmer, it needs a minimum 60-cm aquarium; keeping multiple males together intensifies their competitive color displays. Peaceful and community-compatible, it accepts a varied omnivorous diet. Due to its extremely restricted wild range and habitat pressures, wild populations are classified as Vulnerable on the IUCN Red List; almost all commercially available specimens are responsibly captive-bred.
