A background is made of the cut limestone rocks glued directly to the back wall in the tank. The filter input pipe and heater are hidden behind the background in the left corner. The rocks used in the tank were mostly limestone rocks but there were the periods when I used the light, nearly white rocks. I have to say that the limestone rocks looked best.

I used to keep a various mbuna species and other Malawian cichlids in this tank from its set up in 2002. An initial fish load seemed to be absolutely with no problems. The cause was that the fish were young and silent. A few little fightings were not dangerous. Pseudotropheus demasoni behaved intraspecific most aggressively and I had lost two of them at the beginning. So I added next 5 fish but only one male and 2 females survived. All six Melanochromis interruptus were females and one of them woun't hold it and spawned herself. Later, 3 of them have died due to the bloat. The sex ratio of Labidochromis sp. "Mbamba" was 2:2. Pseudotropheus flavus (1 male and 5 females) and Pseudotropheus saulosi "Coral Red" (3 males and 3 females) spawned regularly. If I wanted to keep the fry I had to strip the female and put the fry in the small tank right before they would be released in the main tank. However, females released the fry in the tank and there they were quickly eaten by other fish. P. flavus were the most successful hunters.

About 2 years later, 6 Neolamprologus buescheri "Zaire Gold" were bought and they coexisted with mbunas with no problems. Read next.
