Species Information
Identification	Corydoras schultzei is usually considered a synonym of Corydoras aeneus. However, there is a school of thought that holds the opinion that Corydoras aeneus should be restricted to the holotype form which is from the island of Trinidad and specifically is not as elongate as C. schultzi. Somewhere across the huge geographic range of "continental" Corydoras aeneus and amongst its several geographic variations, which are really quite different shapes and sizes, sees the species featured here. If for no other reason than to prevent captive hybridisation and indeed to help separate the other forms, the junior synonym is used here as a species in its own right. The black colour form was produced by German aquarists in the '90s and is, confusingly, often marketed as Corydoras sp. "VENEZUELA BLACK". This black colour form does not occur in the wild, has nothing to do with the country of Venezuela or the separate species, Corydoras venezuelanus.
Sexing	Females grow larger and are more full-bodied, this is best observed from above the fish. Males will typically have more pointed as opposed to more rounded fin tips as they mature.
General Remarks	There is a thought the confusion with Corydoras venezuelanus happened due to this thread which is the first use of the term not long after the forum went live, however, the name was being used in wholesale lists well before this point. The earliest record being a list from 2001 Czech wholesaler Milan Ullman.
Habitat Information
Distribution	Imported from Peru.
IUCN Red List Category	Not Evaluated
Husbandry Information
Feeding	Will readily accepted all prepared foods that reach the bottom of the aquarium such as tablets, granules and larger flakes. Live (or frozen) foods such as bloodworm, white worm, grindal worm (Enchytraeus), Daphnia and Tubifex are readily accepted and good for conditioning groups of fishes for spawning. User data.
Furniture	Ideally substrate should be sand, but rounded gravel is an imperfect alternative. Avoid keeping over rough edged (chipped) gravel, this will increase this risk of damage the fishes barbels when it tries to dig. Substrate should be bordered with driftwood and aquatic plants leaving an open area for them to search for food and swim. The shade provided by overhanging rock work, arching bogwood, tall or floating plants are all that is required to settle these fishes.
Compatibility	A peaceful, shoaling, community fish.
Suggested Tankmates	Keep in a shoal of at least 6 individuals - a good first catfish for a beginner's community aquarium - especially the black form which is captive raised.
Breeding	Has been bred in the aquarium.
Breeding Reports	There are 22 breeding reports, read them all here.
