Female.
See the line of blue on the gill plate that almost looks like a "J" in your photo right below the eye along with the 5 spots like on a dice posterior to that? See how the female that GatorXXX420 posted has that but it looks like an "L" since it's the other side of the fish along with the spots? See how the male posted in the same photo by GatorXXX420 doesn't have that at all?
Blue on the lower gill plate is a female trait no matter if it's a small or large amount.
Male-no blue on the lower plate. Blue on the jaw means nothing.
Female with lots of blue on her gill plate.
