Paskai RainbowfishAlso known as Red Neon Blue Eye Rainbowfish. One of the lesser widespread variants of the blue eye rainbowfish, the pseudomogil paskai lives in very large schools in areas with dense vegetation which makes it an ideal candidate for a planted aquarium. It is peaceful with other species of similar size and can even be kept with adult dwarf shrimp. As with many rainbowfish, darker substrate will also often result to better colouration.
