Scientific Name Corydoras amphibelus  Cope, 1872
Common Name
Type Locality Tributaries of Río Ambyiacu, near Pebas, about 3°10'S, 71°50'W, Peru.
Pronunciation Kory DOOR ass
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.

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.

This species has not been imported or photographed - it's something of a mystery. The holotype was supposed to have been lost but it appears it is in the Philadelphia Academy of Science collection. There's not much that can be gleened from it save for the fact that there would appear to be a band across the back like C. rabauti and C. zygatus, but like C. zygatus there looks to be a break in the band just below the dorsal spine. Also the holotype measures just 27.4 mm SL making it either a small species or perhaps a juvenile fish. The short chunky body shape also points towards being a juvenile.
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.
