The Red Neon Blue Eye Rainbow, scientifically known as Pseudomugil luminatus, is a stunning and vibrant species of freshwater fish native to the clear streams and waterways of Oceania. Their eye-catching colors and active behavior make them popular among aquarists who enjoy lively and visually appealing aquariums.

This species is characterized by its slender, slightly elongated body, which provides a bright canvas for its vivid colors. The most distinctive features of the Red Neon Blue Eye Rainbow are its iridescent blue eyes and the intense red-orange coloration that appears on the body and fins, especially when the fish are in optimal health and breeding condition. Their fins are often semi-transparent with delicate hues that catch the light as they swim.

In captivity, Red Neon Blue Eye Rainbows do best in aquariums that simulate their natural environment, which is typically filled with clean, well-oxygenated water and a moderate flow. They appreciate a setup with plenty of space for swimming and some densely planted areas that offer refuge and mimic their native habitats. The presence of dark substrate can also enhance their natural colors.

Social by nature, these fish should be kept in groups to promote their well-being and natural schooling behavior. A group setting not only reduces stress among individual fish but also encourages more vibrant displays of their natural behaviors and interactions, which are a delight to observe.

Their dietary needs are omnivorous and should be met with a variety of foods. A balanced diet for Red Neon Blue Eye Rainbows includes high-quality flake foods, small pellets, and live or frozen foods such as bloodworms and artemia. This varied diet helps in maintaining their health and accentuating their natural coloration.

Breeding Red Neon Blue Eye Rainbows can be a fulfilling endeavor. They often spawn in the morning, scattering their eggs among aquatic plants. The water conditions should be ideal with soft and slightly acidic water. It is common practice to remove the adults after spawning to ensure the eggs are not eaten, thereby increasing the survival rate of the fry.

Overall, the Red Neon Blue Eye Rainbow is an excellent selection for both beginner and experienced aquarists. Their brilliant colors, dynamic swimming, and peaceful temperament make them a captivating addition to any community tank, especially those designed to resemble a vibrant Oceania biotope.
