I had a male and female Melanochromis auratus, the male died a few weeks ago. Now the female has changed color. She was primarily yellow & white with some black stripes. Now she is primarily black a tan strips. She looks more like the male did. She is in a tank with all males. Is it possible she is camouflaging herself to look like a male for survival ? Or is this a normal change for the females to go through? I know it's not a good situation to have her in and I will probably see if my local pet store will take her.
