This is a new strain developed by Somethingsphishy in our extensive Angelfish breeding and research section. As adults they will be a stunning bright true blue on the face and a jet black on the back half with a marble border in the middle between the two colorations. You can only buy them here at Somethingsphishy. We are always willing to try and sex our fish for a customer, but we do not guarantee it. All Angelfish are unique and the coloration/pattern of each can vary. Medium Angelfish have a body size without the fins of approximately a Nickel to a Quarter. They will have a very limited availability.
