About Red Neon Blue Eye Rainbowfish

The Red Neon Blue Eye Rainbowfish (Pseudomugil luminatus) is a vibrant and eye-catching freshwater fish native to the rivers of Papua New Guinea. Known for its striking red body and iridescent blue eyes, this species is a favorite among aquarium enthusiasts. The males display more intense coloration, with fiery red hues that stand out in contrast to their bright, glowing blue eyes. Females tend to be slightly less vivid but still possess a subtle beauty with more muted red tones.

Growing up to 1.5 inches in length, the Red Neon Blue Eye Rainbowfish is small but full of energy. They thrive in planted aquariums with plenty of swimming space and appreciate slightly acidic to neutral water conditions (pH 6.0-7.5) with temperatures between 75-82°F. These fish are social and should be kept in groups of at least 6-8 individuals, which helps them feel secure and display their best colors.

Despite their vivid appearance, they are peaceful and make excellent tankmates for other small, non-aggressive species. Due to their schooling nature, they enjoy swimming in open spaces, though dense planting and driftwood provide necessary hiding places. A varied diet of high-quality flake food, micro-pellets, and occasional live or frozen foods like daphnia or brine shrimp will help them maintain their vibrant coloration and overall health.

The Red Neon Blue Eye Rainbowfish’s small size, energetic behavior, and dazzling appearance make them a standout choice for aquarists seeking a dynamic, colorful addition to their aquarium.
