Sandton Aquatic, Johannesburg

Browse through a loose ensemble of fruit vendors, coffee shops, pet shops, a nursery and - the main attraction - the koi fish shop that also supplies a wide selection of tropical and marine fish. Both national prize-winning koi as well as fish of humbler origins are on offer here and, for fish from a different angle, the Leaping Frog restaurant frequently has sushi on the menu. Sandton Aquatic is situated adjacent to the two biggest shopping malls in the north, Fourways Mall and Fourways Gardens, with Monte Hotel and Casino in the vicinity.
