It's by the color pattern kn the body

Male:

Female:

Notice hPw te male has more color on the body, whereas the female's is duller. Also the females ten to have the jewels on the gill plate behind their jaw.

With smaller fish it is very hard to do this.

I use the gill plate coloring to sex as well. Some females are more colorful than others. This is one of my females.

Try feed small amounts twice daily rather than one big feeding. If she knows food is always available she will know food will be available for the fry. I was told this a year ago and it seems to work. Also make sure she has a flat surface to lay eggs on (mine likes a one slate piece I have). Hope thar helps you!
