Here's something else you can try. Divide your tank into areas by
placing a towering item (I used two rocks) mid tank. I had a problem
with three male Maylandia Greshakei. One Greshakei thought the whole
tank should be his territory. The next time I cleaned the tank I
removed all structures and rearanged, placing two rocks, one about 1/3
and the other about 2/3 along the bottom of the tank. All three now
have taken an area to call their territor. No fight unless one wonders
beyond their "Territor Rock". the best part is that all three now wear
their Dominate Coloring.
