Ray behaviour after breeding

Those who read know i posted a pic of what looked like a sperm plug last week. The male has definitely been trying it on with 2 out of the 4 females in the tank and got himself into trouble on a few occasions resulting in cuts and one sting in the top of the disk. The 2 females are beat up that he has been trying it on with. Now a few days on and the male and one of the beat up females are acting a little strange. They seem happy enough, climbing the glass and swimming around, not burrying in the sand at all. But both the male and female are a little off their food. I have noticed a real change in the amount they are eating. In your experiences has anyone noticed this after rays have been breeding. The male is not trying to flip any of the females now.

Anyone any comments??
I am getting a little concerned now. I am feeding roughly half the amount of food to the tank compared to a week ago. All still acting normal just not eating anyway near what they were, especially the male and female.
