CAT1892S
An aggressive and territorial species whose tankmates should be chosen with care. It can be maintained successfully with other medium-sized Tanganyikan cichlids that occupy different areas of the tank such as Cyprichromis species. Other rockdwellers such as larger Julidochromis or Altolamprologus are possibilities if the tank is large enough and sufficient territories are provided. It can even be kept with mbuna. It is very aggressive towards conspecifics and only a single pair should be kept.
