I had an overstocked/overfiltered mbuna tank. It was one of the prettiest tanks I've ever seen. Constant movement, beautiful colors and the occasional fry peeking out from under a rock. White crushed coral substrate with white/pinkish decorative rocks. Bright blue background with a bubble curtain across the back. People used to knock on my door and ask to see it because it was visible through the front window at night. Awesome tank.
take care
