Down arrow Cat-eLog Data Sheet
Scientific Name Corydoras(ln1) heteromorphus  Nijssen, 1970
Common Name
Type Locality Creek at right bank of Coppename River, Saramacca, 3°52'30''N, 56°53'W, Suriname.
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. This specific epithet literally means different (heteros=different, other) shape (morph=shape, form).
Down arrow Species Information
Size 53mm or 2.1" 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.

Down arrow Husbandry Information
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.
Breeding Unreported.
Breeding Reports There is no breeding report.
