Definitely male. If you look at the last picture in the original post you can see his belly (that greyish circle behind his pectoral fins as he turns away from the camera) right behind that is empty. If he were a she you'd be able to see a tanish yellow triangle right behind the stomach.
He's gorgeous though!
