These are mostly silver as juveniles with just a slight hint of green on the head. Many, but not all, have some black bars in the body. As adults they will develop a vivid olive green in the fins and on the head. 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. Small Angelfish have a body size, without the fins, of around the size of a dime.
