These will be between 2.25 and 2.75 inches with most of them being 2.5 inches. These are a pale ivory as juveniles. As they mature the ivory will turn into yellow-light gold coloration and then will deepen ending a beautiful intense golden-orange when fully mature. 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.
Gallons needed per inch of Discus: 1.5 for 2", 2.5 for 3", 4 for 4", 6 for 5", 8 for 6"
