The Red Neon Blue Eye Rainbowfish, (Pseudomugil luminatus) is one of the lesser widespread variants of the Blue Eye Rainbowfish and is native to New Guinea, Indonesia. It lives in very large schools in areas with dense vegetation, so it is an ideal candidate for the planted aquarium and especially enjoys the cover of floating plants. Males display vibrant neon red to red-orange and blue coloration on their bodies and fins, particularly while competing with other males. The second dorsal and anal fins of males become very extended and fan-like with maturity. Females are typically smaller with shorter fins, but still usually display vibrant coloration.

The Red Neon Blue Eye Rainbowfish is peaceful with other fish species of similar size and can even be kept with adult dwarf shrimp. The most intense color will be displayed when this fish is kept in schools of 6 or more, including multiple males, in a heavily planted, spacious aquarium to ensure that subdominant males are not overly harassed by dominant males. As with many rainbowfish, darker substrate will also often result in better coloration.

Acclimating fish:

• If received after 24-48 hours, slow drip acclimating fish to quarantine tank.
• If received after 2+ days, equalize water temp by floating bag. Try not to pour bag water into aquarium, drain over net externally and drop fish into quarantine tank.
