She looks like a female to me. A trick to identify a female JD is to look at the lower gill plates. If there are green streaks, it is a female. Male has no color on the lower gill plates but a lot more color the head, body and fins.
hmm all 4 of mine have the red on teh top and they all have color int he gills, some are brighter then others though. I thought the bright ones were female and the ones with less were males?
does anyone have a good picture of a female's lower gill plates? so i could see the difference between a male and a female (that would prolly mean i would like to see a picture of a male's lower gill plates as well)
