Mikrogeophagus is a genus of cichlids native to the Llanos wetlands (Orinoco basin) and Guaporé–Mamoré river system (southern Amazon basin) in tropical South America.

[2] They are dwarf cichlids that reach up to 6 cm (2.4 in) in standard length.

[2][3] They are popular with aquarists, especially M. ramirezi.

These species spawn on flat rocks or leaves and not in small caves like the closely related cichlid genus Apistogramma.
