First, we could use a bit more information about the tank that houses your rams:
What's your tank-size [volume and surface area]? Is it planted? Are their caves and other hiding places? What other fish are housed in it? How long have you had them? How old are they?
Answers to these may help.
As for feeding, my female is super active at feeding times while my male tends to hang back. I don't know if that is normal, but that seems to be how it goes with mine. they do best with, it would seem, with smaller pellets than with wafers so I always break the wafers up a little. But if they have nice full bellies, then whatever they are doing it is fine.
Finally, if you want, you could post some pictures to make sure that they are the sexes that you think they are.
