Neon Turquoise Discus Fish. The neon turquoise discus is a calmingly beautiful tropical fish for your freshwater aquarium. The neon turquoise discus results from selective cross breeding among the naturally occurring green and blue discus until offspring displaying the bright turquoise color were achieved. These were then bred further to eliminate the stress bars of the wild discus. The neon turquoise discus is a solid, almost glowing turquoise color, although the exact shading varies from fish to fish. The body of the neon turquoise discus is a solid blue-green color, but it has an area of shading in the center of its body that is much darker than the rest of the fish. Its head has a light pattern of red striations. Both the pectoral fin and the dorsal fin of the neon turquoise discus are covered with the same red striations, and its tail fin is a dark, opaque color.Discus are known for their size, their vivid colors, and their rounded bodies. The neon turquoise discus reaches about 8” at its full grown size, and it is almost as tall as it is long. Both the dorsal and pectoral fins of the neon turquoise discus extend almost back to its tail fin, which contributes to its pleasantly round shape. The neon turquoise discus is one of the most beautiful cultivated discus. This bright, sea green beauty is a great showpiece for an aquarium, and will add a calming touch of beauty and charm to your collection of tropical fish for your freshwater aquarium.
