Small Angelfish have a body size without the fins of approximately a Dime. These are Greyish-Green as juveniles and will start to show much more green as the mature. The Black coloration on the back half will come and go with stress, so do not be surprised if they do not show much at delivery. 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.
