Scientific NameCorydoras ehrhardti  Steindachner, 1910
Common Name
Type LocalityAffluents from Jaraguá mountains, new Joinville, Brazil, 26°21'S, 48°49'W.
Synonym(s)Corydoras meridionalis
PronunciationKory DOOR ass - err HART eye

Size 55mm or 2.2" SL. Find near, nearer or same sized spp.
IdentificationCorydoras 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.
SexingFemales 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.

FeedingWill accept a wide range of commercial foods including tablets, granules and flakes. Live (or frozen) foods such as bloodworm, white worm, grindal worm, Daphnia and tubifex are readily accepted.
FurnitureShade provided by overhanging rock work, arching bogwood, tall or floating plants are all that is required. 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.
CompatibilityA peaceful, shoaling, community fish.
Suggested TankmatesAll Corydoras should be kept in groups of at least 6 of the same species. Otherwise compatible with most other types of fish that are reasonably peaceful, as long as they don't see a Corydoras as a snack.
BreedingHas been bred in the aquarium.
