havbing to agree with the other two, angels and other taller cichlids would do better in that type of tank (ie, discus, severums, uarus )...however, if you really want to go with an african cichlid community, try to build the rocks up to the top so you have fish at all levels, not just crammed into a smaller space...also, try putting in some air stones to off set the lack of surface area...you may run into stocking problems, since africans are usually recommended to be kept in overstocked tanks to prohibit fighting, overstocking your tank doesnt take very many fish...good luck in your decision
