Red Neon Blue Eye Rainbowfish (Pseudomugil luminatus), Tank-Bred

Species Overview

The Red Neon Blue Eye Rainbowfish (Pseudomugil luminatus) is one of the most colorful nano fish available in the aquarium hobby. This stunning species combines glowing blue eyes with vibrant red-orange body coloration and brilliant red finnage, creating a display that often appears almost fluorescent under aquarium lighting.

Despite their small size, Red Neon Blue Eyes are remarkably active fish that bring constant movement and color to planted aquariums. Males frequently display to one another, extending their fins and intensifying their colors in an effort to impress nearby females. These displays are completely fascinating to observe and are one of the reasons this species has become so popular among nano aquarium enthusiasts.

Our Tank-Bred and Locally Bred Red Neon Blue Eye Rainbowfish are well adapted to aquarium life and make excellent additions to planted community aquariums. Locally Bred specimens are typically offered at a larger purchase size, making them an excellent choice for hobbyists looking for more developed fish with emerging adult coloration. When maintained in groups, these fish display their best colors, most natural behaviors, and highest activity levels.
