Grow the white one out. Are you keeping the fry in the tank with her and the male?
My Malawi Cichilds breed like that before we move. They are starting up slowly again. When we moved I had a 18gal rubber maid container with about 300-400 fry/ juvies ranging from .5 inch to about 1.5 inch. I wish I could have kept them and grew them out but too much stuff going on with moving and had to sell them back early and only got $30 worth of sore credit.
