Cat-eLog Right Arrow Callichthyidae Right Arrow Corydoradinae Right Arrow Corydoras

Jump to next section Cat-eLog Data Sheet
Scientific Name Corydoras sterbai  Knaack, 1962
Common Name(s) Sterba's Cory
Panzerwels (Germany), Sterba's Corydoras
Type Locality Rio Guaporé, Brazil.
Pronunciation Kory DOOR ass - ster bye
Etymology Cory = helmet, doras = skin. In this case it was incorrectly used to mean armour (cuirasse) instead of skin in allusion to the dual rows of plates that run along the flanks of this genus. Specifically named in honour of Dr. Günther Sterba.
Jump to next section Species Information
Size 65mm (2.6") SL. Find near, nearer or same sized spp.
Identification Corydoras are identified by their twin rows of armour plates along the flanks and by having fewer than 10 dorsal fin rays. They are most commonly confused with the other genera in the sub-family, namely Brochis, Scleromystax and Aspidoras.

It is hard to misidentify this species but it can be confused with Corydoras haraldschultzi, although the latter is a long nosed species where C. sterbai is the dome headed form - the easiest way to tell them apart is that the Sterba's Cory has white spots on its head from eyes down to snout. C. haraldschultzi does not. Corydoras sterbai has recently become available in albino form.
Sexing Males are smaller and slimmer. Females grow larger and are much wider; most easily observed from above.

Jump to next section Husbandry Information
Feeding Readily accepts a wide variety of frozen and prepared foods in the aquarium.
Furniture Shade provided by overhanging rock work, arching bogwood, tall or floating plants are all that is required. Ideally substrate should be sand, but rounded gravel will suffice.
Compatibility Peaceful. Tank raised fish are ideal first catfish for a beginner's community aquarium. Wild caught fish will tend to be more expensive and somewhat less hardy.
Suggested Tankmates Keep in a shoal of at least 6 individuals ideally with similarly sized tetras and dwarf cichlids. A good species for the discus aquarium.
Breeding See Shane's World article (link below). 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.

I currently hold 40 in a 1050 liter tank and they spawn more or less every day - to the great pleasure of the athor fish in the tank, some which I think have the eggs as their primary food. I have a hard time harvesting eggs as they are litterally eaten in a matter of seconds, rarely more than 30 seconds. As a response to all the eggs being eaten right of the windowpane they have turned more and more to laying their eggs on plants or else where in the tank. I´ve seen one that must have grown up in the new tank, and I guess there are more in there somewhere. Because the sexratio is all wrong I have had a lot of unfertilized eggs and plan on taking them out for a serious breeding session.
