As juveniles, these are a very pale white/yellow. As adults, these are pure as the driven snow. Solid white with no discolorations! They are often called Snow Whites. 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.
