i have a platy in a 46, he is male and there is 1 more male and 2 more female platies, 4 total. he was being picked on a lot by the other platy, and would hide behind a plant and not move, unless it was eating time. so i took the "mean" platy out to see if it would get out behind the plant, and he has not. he is still there, his fins are not clamped either... what do i do with him?
