The rings on these are just starting to differentiate from spots. By five inches, many will be mostly rings. Many will end up being squiggles, not rings. The amount and type of pattern on them can vary significantly. 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.
