So does anyone have information on this? I have a female ray that is biting my male rays. I have been noticing in the past 2 months that both of my males are getting banged up. I have 4 females in and only the males are being bitten. Is this common? What does this mean? Everything I hear or read the males are usually doing the biting. When I am watching them in the tank I see NO aggression. The males are about 12” and females are about 14” everyone is super active and they all eat like monsters. Why are my males being targeted?
