I have 5 platys, 3 female red Mickey Mouse, 1 male sunburst wag, and 1 female sunburst wag. In the last couple days, I have noticed that the female sunburst is almost always swimming by herself. She will go over and swim with the other four, but she is usually alone. Sometimes she acts like she is intimidated by the other four, though I haven't noticed any aggression on her part. When I feed them, she does not feed near the others and will only eat off by herself. She doesn't clamp her fins all the time; in fact she usually isn't clamped, though I have noticed her clamped a couple of times. Is she being bullied? Or is she a loner? I don't want to have to rehome her, but I don't want her to be miserable either. Any insight is welcomed! ETA: She is the latest addition, and it has been about 5 days. Could it just be the "new kid" type thing going on? ETA 2: I just watched my male dart after her. He seemed pretty adamant. Could it be that he decided she wasn't good enough for his harem?
