If those are from my gene line, what you describe should be males. The females do not show that coloration. The dominant male will show the most color and will have red markings on the edge of his fins. Really striking. Males are easy to sex when they color up by looking under the hood. Pretty obvious when compared to the female.

If you drop some food in the tank, a holding female will either not feed, or go for the food and shy away before taking any. I usually will isolate holding females from the rest in their own tank. Once they spit I fish them out and put them back in the breeding tank. Holding females will look like they are constantly chewing something, and their throats will start to bulge out as the eggs grow to fry.
