These will be between 2.25 and 3 inches with most of them being 2.5 inches. Juvenile Golden Dragons have a light gold to red on most of the body. As they mature, they turn to a deep gold. Many of these will have much more patterning than the one pictured, other will have almost no pattern on them. Golden Dragons are derived from the Pigeon Blood strain. The picture is of an adult. Juvenile coloration and pattern will vary. Sexing mature Discus is difficult and sexing juvenile Discus extremely difficult. We are always willing to try and sex our fish for a customer, but we do not guarantee it. All Discus are unique and the coloration/pattern of each can vary. The Discus you are purchasing is a juvenile. Discus will not show their full pattern and final coloration as in the picture until fully mature at around 5-6 inches.
