Mbuna Pecking Order

[CameronCade]

I have this blue zebra (I think) and it is a male (long anal fins, multiple spots). He has been bullying (more like chasing other if they get in his territory) a female blue zebra for few months now. I come home to see a change in the pecking order. She is now chasing him and he is cowardly swimming off. Also the female is a little smaller than the male. I was wandering what happened. Did she just finally whipped his butt? I don't see any damage to him plus he doesn't flare his fins now. He tries to hang out by the filter now or in the corner under some rocks. He is eating and looks healthy. Just wandering what happened?????

Probably another male the same exact thing happened with my red and blue zebra. He's been boss since.
