Thick pectoral fins on all fish. Wide male head shape, nose point, if you get up real close to them you will see tiny hair bristles along the pectoral fins this is another indication that cannot be seen in the pictures.
We all know how difficult it is to identify the sex of these fish, so please post a picture in here and we'll try to help you (or at least give an educated guess!).
