These will be between 2 to 3 inches with most of them being between 2.25 to 2.75 inches. The pattern on these will very considerably from Discus to Discus. Some will have a full pattern, some will have very little pattern and some will have spots. They will not show their full pattern until they are mature. Red Turquoise Discus are not derived from the Pigeon Blood strain. Juvenile coloration and pattern will vary. 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 mature 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.
