Geophagus is a genus of cichlids that mainly live in South America as far south as Argentina and Uruguay, but a single species, G. crassilabris is from Panama. [1] [2] They are found in a wide range of freshwater habitats. [3] They are part of a group popularly known as eartheaters and mostly feed by picking up mouthfuls of sediment to sift out food items such as invertebrates, plant material and detritus. [3] The largest species reach up to 28 cm (11 in) in standard length. [3] They are mostly kept in aquariums. [4]

Some cichlids previously included in this genus have been reallocated to Biotodoma , Gymnogeophagus or Satanoperca . [5] Even with these as separate genera, Geophagus is currently polyphyletic and in need of further taxonomic revision. There are three main groups: [3] [6] [7] [8]

Mesonauta is included in the subfamily Cichlasomatinae. They occur in various freshwater habitats such as streams and lakes, especially in areas with little water movement and aquatic vegetation. They are generally found in small groups that stay near the water surface. To avoid predators, adults may jump out of the water and juveniles mimic leaves.

Apistogramma nijsseni is a species of cichlid fish, endemic to highly restricted local black water habitats in the Quebrada Carahuayte, a small stream in the Ucayali River drainage, southern Peru.

Apistogramma brooding females assume a bright yellow and black aposematic coloring: in A. nijsseni, unusually, a healthy, unstressed female retains this coloring. The species is popular aquarium fish amongst dwarf cichlid hobbyists, though it does not often appear in the general pet fish market.
