Turquoise Rainbow Eel & Knifefish well-maintained aquariumRainbow fish are beautiful! They come in many different colors and can create a beautiful school of color in community aquariums. They generally reach about 4. 5 5 inches and should be kept in groups of six or more. We recommend 40+ gallons. They are peaceful and are usually kept with other community fish around their same size. Some examples are angelfish, large tetras, Plecos or Cory catfish.
