Yellow Bosemani Rainbowfish

The Yellow Boesemani Rainbowfish is a stunning variant of the Boesemani Rainbow, showcasing a bright golden-yellow to orange rear half with a softer bluish front, depending on individual and lighting. Native to West Papua, Indonesia, these medium-sized rainbowfish are active swimmers with peaceful temperaments, making them a striking addition to community aquariums.

This species is moderate in care, requiring stable water parameters, schooling companions, and well-maintained aquariums to thrive and show their best coloration.

• Temperature: 24–28 °C

• pH: 6.5–7.5

• Water Hardness: Soft to moderately hard

• Temperament: Peaceful, schooling, active

• Diet: Omnivore — high-quality flakes, micro pellets, frozen foods, and occasional live foods like brine shrimp or daphnia

Behavior & Compatibility:

Yellow Boesemani Rainbowfish are peaceful, active schooling fish. Keeping them in groups of at least 6 encourages natural behavior and reduces stress. Compatible tankmates include:
