The most common African Cichlid aquariums consist of either Lake Tanganyika or Lake Malawi cichlids. It is suggested not to mix these two groups together due to character and dietary differences. Both types of set-ups would generally consist of large quantities of rockwork combined with a fine substrate, gravel or sand. These fish dig, so careful attention should be paid to setting up rocks, to avoid possible collapses. Plastic plants can be used or live plants such as species of Vallisneria or Anubiascan be attempted.
