Red Neon Blue-Eye group of 4 males only.  This species is stunning.  

The Red Neon Blue-eye (Pseudomugil luminatus) is a dazzling nano fish that brings vibrant flashes of color and activity to the freshwater aquarium. These tiny fish reach a maximum size of about 1.2 inches (3 cm) and are admired for their glowing red-orange bodies, electric blue eyes, and delicate, flowing fins edged in iridescent highlights. Best kept in groups of six or more, they are lively schoolers that display fascinating social interactions and feel most secure and vibrant when in the company of their own kind. Ideal water parameters for P. luminatus include a temperature of 72–80°F (22–27°C), a pH between 6.0 and 7.5, and soft to moderately hard water (5–15 dGH). Despite their bold coloration, they are peaceful and gentle, making them excellent companions for other small, non-aggressive fish in a well-planted community tank. Their stunning colors, graceful movements, and curious nature make the Red Neon Blue-eye a standout choice for aquarists looking to add a spark of brilliance to their aquarium.
