so i have a 6" male ray and he has 2 white spots looks like one of the female rays are sucking on him. the female rays are 7-8 inches. is this common with rays. i was thinking about separating them. i was thinking of pulling the male out and reintroducing him later on when he gets a bit bigger or would the female just be very territorial when i reintroduce him? hope i make sense. btw water is ammonia 0 nitrite 0 nitrate 0.
