I have kept Neolamprologus multifasciatus ( I think I spelt that right... ) and I they didn't seem to keen on plants the tank the male would attack the java ferns randomly as it was in "his" territory he wasn't out to eat it just to attack it .
They love to dig and make mounts as well as dig out their shells from under the sand or whatever substrate you use. I was using the African Cichlid Mix, the fine stuff. They were always "rearranging" the tank and moving substrate around, usually whenever it was time for a spawning. The females took turns with the male and whichever one was in spawning mode she would move the substrate around.
Here is a pic of the male I had:
