Man getting confused with the new forum but your Jag is a female well should be anyways Ive heard of females looking like males but never a male looking like a female. Females keep the big middle bloches males dont the turn to small spot females bottom spot stay light in color male stay dark the blue color on the ends of the tail is apparent in male and female. Most jags get very aggressive males more so then females except for some rare occasions besides mating. Ide bet a hundred dollars that its a female. So hope this helps.
