These will be between 2 to 3 inches with most of them being between 2.5 to 3 inches. These are a beautiful brilliant blue as juveniles and already have most of their coloration by two inches. As they mature the blue will become more shimmering ending in a beautiful intense almost flourescent blue when fully mature. The amount and type of pattern on them can vary significantely. 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.
