Here are some descriptions from the SCHINDLER & STAECK 2006 paper:
"Geophagus gottwaldi sp. n. is described from the drainage of the upper río Orinoco in
the Estado Amazonas in southwestern Venezuela. It can be distinguished from all other described
Geophagus species by the following combination of characters: a prominent dark infraorbital stripe,
caudal fi n with a pattern of roundish light spots, a rectangular midlateral spot, 34–36 scales in a
lateral line and total length of more than 20 cm."
A few pictures from the paper of preserved (first) and live (others) Geophagus gottwaldi
This is a pic of Geophagus taeniopareius from the same paper for comparison:
