Solid Cobalt Discus Fish
. This discus will make an interesting addition to your tropical aquarium due to the extensive change in coloring it undergoes. The solid cobalt discus has been crossbred to produce a solid colored body devoid of markings, but the markings are visible in a juvenile. When first born, the fry of the solid cobalt discus is an almost translucent blue color. The color deepens, and the young solid cobalt discus will display stress bars and striations of its naturally occurring ancestors. After three or four years, all of the markings from its body will have disappeared, leaving just the vivid blue coloring. The face of the solid cobalt discuss will retain its darker colored striations. The pectoral and dorsal fins will also continue to have a pattern of dark striations, but its tail fin will be free of markings.
Discus are known for their flat, round shapes, bright and unusual colors and markings, and their large size. At maturity, the solid cobalt discus will be 8” long. Its body is almost as tall as it is wide, which gives the discus its rounded shape. The pectoral and dorsal fins of the discus are very full, and they cover most all of the length of its body, which adds to the round appearance of the solid cobalt discus. The solid cobalt discus is a stunning tropical fish, and it will enhance the variety of vibrant colors in your freshwater aquarium. The beautiful blue coloring will stand out among all of the fish in your aquarium.
