Males will also be bigger and appear to be longer/pointier in shape.
Females will be smaller and more stout in shape.

Females will have blue splotches on the bottom of thei gill plate...
Males will lack blue splotches on the bottom of their gill plates although may have a stray spangle or two in this area...
If the fish are young it is very likely they will be very hard to sex and will commonly show signs of the other gender. Sexing Dempseys before they are sexually mature is very difficult and is rarely reliable.
The "pointed fin/body" theory suggesting male is very commonly incorrect. I have a tank full of juvi JDs currently and the dominant females have pointier fins than the sub dominant males. This is very common. I also have found body shape is much more of a genetic heredity than it is a suggestion of gender.

Notice the difference between the females facial area compared to the male?

The above pics (Thanks NBK) are a great display of my above point... the male has quite rounded fins... at least one of the females appear to have much pointier fins...
^ Yep the females that I have kept have had beautiful pointed fins and the male I have has a nice rounded edge.
This simply makes me not trust the pointed fins are males method - clearly for my cases it didn't work.
I think if you look at the markings and the body shape this will give you a far higher chance of more accurate sexing.

Thank you for your responses. That is very helpful and there is alot of conflicting information that people pass around. The blue ist he easiest way to tell.
