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!).
It's hard to tell from this angle, but I belive it's a male. Based on the size of the first ray of the pectoral fin, the size of the odontodes, and also - the shape of the fins. But I've been wrong before
Pandadosmares,
I think SHE is a Male. Although the photograph is not very clear, you can see the very long cheek odontodes, which amongs others ,are the characteristics of a male.
