Geophagus sveni is a Geophagini cichlid native to the Tocantins River drainage in Brazil.
[2] Geophagus sveni is a medium-sized cichlid that reaches approximately 225 mm (10 in) in standard length (SL), and is usually found in the Tocantins River basin.
Similarly, Geophagus sveni has a typical teleost encephalon, without significant intraspecific variation and hence without dimorphic traits.
[3] The fish is named in honor of Sven O. Kullander of the Swedish Museum of Natural History, for his many contributions to cichlid systematics.
