The female is still very quiet and not hiding but staying out of the way.
She couldn't be sick, surely she would be over it by now,it's been 5 days.
I think I will move her to the 5 footer my brother and I have set up between us and give her a spell from the male for a while,as there are only guppies in that tank should be stress free.
May even give them a week about, give them 2 weeks apart,a week each in the 5 footer,get them back in the swing of things.
If that does not work may have to exchange the female.
