Sterba's Corydoras grows to some 6cm long. It has two distinguishing features from known similar corys. Firstly it has an orange edge to its pectoral and pelvic fins. Secondly, its spotted head pattern is of white spots on a dark (brown/black) background, whereas the Mosaic Corydoras, C. haraldschultzi and C.045, C. araguaiaensis, have black/brown spots on a light (white) background.
Sterba's Corydoras variant This fast-diving, apparently all-striped individual is suspected to be a Sterba's Cory despite the apparent lack of a spotted head, since it was with Sterba's and it has orange-edged pectoral and pelvic fins.
