Twisted Penguin yours doesnt have the preopercular bar (small black bar in front of gills) and it lacks the lateral spot or has a very small one.
Ed what are the distinguishing characteristics of brachybranchus compared to the other species? I tried to look on cichlid room companion but they dont have this species described

Twisted Penguin... your G. altifrons has an abdominal spot that is 2-3 scales in size and often not expressed (as in your picture), your fish also has no facial markings, where the fish in the original post clearly has a pre-opercular mark (gill plate). Very easy to distinguish by those traits.
abarilot... They can be distinguished from all Geophagus other than proximus, dicrozoster and winemilleri by their pre-opercular mark, G. dicrozosters Y band through the abominal spot distinguishes them, G. proximus has a large squared abdominal spot where G. brachybranchus has a rounder one (can appear tear shaped), and G. winemilleri has a striped tail not spotted like G. brachybranchus. Though technically one of the paratypes for winemilleri has a spotted tial (??) and there also seems to be some G. cf. proximus with a normal spot (mostly in Europe), but generally those are the differences.
The description of G. brachybranchus by Kullander (pg 48-56) can be read here...

The pre-opercular spot is discussed on page 49 (second paragraph) and you can faintly see it in the image of the holotype.

Everything you ever wanted to know about Geos and were afraid to ask :-O Thank you so much for your pictures, Andy. I'm on my way to study that link.
