Yeh I had noticed my red zebra chasing my yellow lab for weeks and the red zebra female. And I finally found out she was brooding. But that wasn't until I added 3 more female mbuna to the tank and she finally had less stress from
the males that she released them. And since then the aggression and chasin stopped completely. Now with the new peacocks I just had a few mins of circling amongst themselves to establish who was too peacock. The mbuna aren't paying them any mind and they ve slipped in seamlessly I'm glad I could save these 2 from the tanks they were being beaten up in. The alunocara was hiding in the back corner behind decor. If I hadn't climbed the employees step ladder I never would have seen him cowering in the back. Now he's got 125 gals of freedom.
