Solid Discus fish add a vivid color blast to the Freshwater Aquarium. We carry from solid red Discus Fish to Solid green Discus Fish with all hues in between. I often hear... "I have a heavily planted freshwater aquarium and think the solid blues or greens will blend in with the plants." Don't worry, they won't... All of the colors are either extremly metalic or vivid that they actually pop out on a freshwater planted aquarium background.
