Red Neon Blue Eyed Rainbow

Red Neon Blue-Eyed Rainbowfish (Pseudomugil luminatus)

The Red Neon Blue-Eyed Rainbowfish is a dazzling nano fish admired for its brilliant red-orange body, shimmering blue eyes, and constant, energetic activity. Native to the clear streams and wetlands of New Guinea, this striking species has become a favorite among planted aquarium enthusiasts for its vibrant coloration, peaceful nature, and captivating display behavior. When kept in groups, their flashing colors and graceful movements create a spectacular visual display.

Red Neon Blue-Eyed Rainbowfish are active, social fish that thrive in schools and spend most of their time swimming throughout the middle and upper levels of the aquarium. Males display more intense red coloration and extended finnage, especially when courting females or competing with one another through harmless display behaviors. Despite their lively nature, they are exceptionally peaceful and make excellent companions for other small, non-aggressive community fish.

These beautiful rainbowfish thrive in well-planted aquariums with gentle water movement, open swimming areas, and patches of dense vegetation for shelter. Floating plants and subdued lighting help enhance their colors while making them feel secure. Stable water conditions and excellent water quality are essential for long-term health. A varied diet of high-quality micro pellets, crushed flakes, frozen foods such as baby brine shrimp and daphnia, and occasional live foods will help maintain their brilliant coloration and encourage natural breeding behavior.
