Today for the first time I noticed bite marks on one of my female motoro rays. One bite actually left a gap in her disk. In the tank (300 gal) are 4 rays, 3 female and 1 male. The male is not mature and I would guess will not be mature anytime soon (8" disk) while the female are all larger. They are fed about 3/4 lb. of a mix a fish, shrimp, and pellets each day. Who do you think is the aggressor and what can I do to stop it?
 
i would watch them and see who during feeding is most aggressive.

if it doesn't happen at feeding, watch their attitudes towards each other at various times.
it's hard for us to tell you who the aggressor is, having no background or insight into these specific rays.

once you find out, maybe separate that ray.
