Melanotaenia boesemani
Boeseman’s rainbowfish is one of the most popular Melanotaenia, native to Lake Ayamaru region of West Papua. Mature males show a striking colour break—often blue-green anterior and yellow-orange posterior (colour varies with mood and health). Active and peaceful, they need a long tank with open swimming space and a group of at least six to colour up and behave naturally. Slightly alkaline, moderately hard water suits them; good filtration and frequent water changes improve fin and scale condition. Egg scatterers among fine plants; no parental care.
Quality flake or small pellets; frozen brine shrimp or daphnia; spirulina; varied diet for best colour.
Frequency: 1–2× daily
Colour dulls in poor water or bland diet; males display best in groups.
