Komeng River Rainbowfish (Melanotaenia sp. "Komeng River")

A rare and beautiful undescribed freshwater rainbowfish from the Komeng River in Papua. Prized by enthusiasts for its striking light blue body, navy lateral band, and red accents, this locality form is a true collector’s item in the hobby.

Key Features

• Maximum Size: ~7–8 cm / ~2.8–3.1 inches SL (typical for similar Melanotaenia).
• Appearance: Light blue body with a prominent navy lateral band and vibrant red accents in the fins.
• Fin Details: Typical for the genus with prominent dorsal fins.

Aquarium Care

• Tank Size: Minimum 40 gallons for a small school (6 or more recommended for best coloration and natural behavior).
• Water Parameters: Tropical freshwater; 75–82°F (24–28°C), pH 6.5–8.0, moderate hardness.
• Diet: Omnivorous — readily accepts high-quality flakes, pellets, frozen, and live foods.
