Cant go on dorsal shape, both males and females have pointed dorsal fins. The photo isn't 100% clear, but going on my experience with a couple of types of Freddie I would say that's a female. Males have a lot of spots in the dorsal, anal and tail fins trailing out towards the tip. I have 2 female La Ceibas with different body patterns, but both only have a few spots around the base of the tail. I don't see that many spots on that fishes tail/dorsal etc.
