Depends what you had in mind...
You could do many "dwarf cichlids", but with some of the more fiesty species like Kribs or Steatocranus spp., you would want to keep stocking very low, litterally a good sized group of ditherfish.
You could do a selective small scale Tanganyikan tank; eg. trio hareem of "Sumbu dwarf"; pair of Julidochromis dickfeldi; pair of Neolamprologus puncktatus. Then watch the numbers multiply and how they all interact.
