Hi, everyone. I just bought three angelfish. I bought one gold marble (Francesca), a marble veil (Louie), and a smokey blue leopard veil angelfish (Leo). The gold marble is slightly larger than a quarter (not including the fins) and the other two angels are around 3-4 inches. I was wondering if anybody has any way of telling the sex of these angelfish as I would like to know out of curiosity. If you breed angelfish, it'd be nice to hear of traits that are commonly seen in male angelfish and traits commonly seen in female angelfish such as fin shape, head shape, behaviour, etc... Thank you for your help!
