Help! I don't know what to do. I have 2 Mickey Mouse platy's in a 1o gallon cycled tank. 1 is male and one is a pregnant female. My male Yellow is driving Red (her) nuts. He is constantly trying to mate with her. I tried to introduce a new female but she was ignored and died this morning. I don't know if I should try and introduce another female again or just leave them be. Please help me!
