Mysterious Platy Death

[DYLANSDAD022102]

i dont what the problem is. one of my preggers females just started jolting around and acting funny and then just stopped. all my water peramiters are perfect. 50% water chages every week. i dont know if she was bullied to death because there is another preggers female and the male platies just wont leave the ladies alone. should i separate them? i dont know my first attempt at breeding so im unsure.

Yes the stress of him chasing her could kill her.
Was she due to give birth.
Any physical signs to go on.
