Gertrudae RainbowfishThe Gertrudae Rainbowfish, also known as Spotted Blue Eye or Gertrude's Rainbow, is a beautiful small sized variety of the blue eye rainbowfish which thrives in very large schools in areas with dense vegetation making 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.
