Scientific Name Corydoras diphyes  Axenrot & Kullander, 2003
Common Name
Type Locality Small stream (arroyo) at Estancia María Belén, 8 kilometers from Colonel Patricio Colman, 25°40'13''S, 55°05'52''W, río Paraná drainage, Depto. Caaguazú, Paraguay.
Pronunciation Kory DOOR ass - die fees
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. Diphyes, from the greek word meaning double nature; in reference to the unique (?) variation in colour patterns expressed in this species (striped and spotted).

Size 50mm or 2" 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.
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.

Feeding Will 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.
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 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.
Compatibility A peaceful, shoaling, community fish.
Suggested Tankmates All 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.
Breeding Has been bred. Breeds after 50% water change with water around 14°C.
