Description: Attractively coloured Cory with yellow pectoral fins. Most of the body and fins have a black base color with silvery white markings. Very similar to Corydoras haraldschultzi, but Sterba's Cory has white spots on its head from eyes down to snout, and Corydoras haraldschultzi is a long nosed species. Also available in albino form, identifiable from the Bronze Cory albinos by still displaying an orange/yellow tinge to their pectoral fins. Corydoras sterbai does not seem to mind higher temperatures, so they are ideal tankmates to Discus fish. Wild caught fish usually more expensive and somewhat less hardy.
Males are smaller and slimmer, while females grow larger and are much wider. It is most easily observed from above. Tank-bred specimens that are frequently found in the shops appear relatively easy to breed, where wild-caught specimens are reported to be a bit more difficult. Before breeding give them good diet and repeated water changes and drops of temperature can initiate spawning. In characteristic Corydoras fashion, the female deposit the eggs to the aquarium glass. The eggs hatch in 3-5 days and once the fry have used up their yolk sacs, they'll accept microworm and brine shrimp nauplii as first foods.
