how can I identify a female from a male jack dempsey?

I’ve got a jack dempsey that I’m trying to sex for breeding…anyone have experience with this?

    I would like to say…Do you know if you have a male or female? The male will always be the more dark, and prodominant color paterns over the female. I had African Albino Frogs that I used to breed and get may tadpoles from, but still have never seen any of my cichlids ever have babies. A friend of mines 40gal tank, has a batch of fish almost every couple weeks! Convicts and a Parrot. Just keep double the filtration going, and keep the heat around 76 degrees and you’ll have a great mating grounds for your fish!

    The bigger & prettier fish will be the males. But you will need afew females for him to chose from. You will need to variy the temp a lot and do frequent water changes during storms to imitate water runoff which will help get him in the mood. Having a second male will help to as he will fell that need to compete for the ladies. Ive found it to help loads when the femals grow-up seperate and i will combine them for a few weeks in the same tank. Later to remove the males seeing they like to be rough with the ladies. :) also check to see if your fish are indeed teh exact same species as they want do international relationships. Some males even change color as they become the dominante fish or during the mating cycle.

    I would like to say…The males are normally darker and have more of like a forehead.Females are lighter and are more streamlined.

    Had a mated pair of demseys’, male was larger with a protruding forehead. When the male chose the female they killed off the other female in the tank, also once mated they did not tolerate any other fish in the tank except pleco (which was considerbly larger)
