Scientific Name Corydoras julii  Steindachner, 1906
Common Names Julli Cory
Almindelig Leopardpansermalle (Denmark), Leopard Cory, Panzerwels (Germany)
Type Locality Creek into R. Parnaíba near Alto Parnaíba (= Victoria), 9°08'S, 45°56'W, Brazil.
Pronunciation Kory DOOR ass - JOOL ee eye
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 species was named to honour a man, but this man remains a mystery.

Size 55mm or 2.2" 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.

Often you will see fish for sale as Corydoras julii but they are actually Corydoras trilineatus. So, if you bought as fish as julii, it's almost certainly C. trilineatus from the upper Amazon. The real C. julii will turn up from time to time as although it originates from the upper Parnaiba system in the lower Amazon drainage, it is found in the Rio Para where commercial fish collectors operate.

Telling them apart without locality information is actually quite hard as some C. trilineatus can show the spotted head pattern traditionally associated solely with C. julii, C. julii appears also to have a shorter horizontal mid body stripe not reaching half way along the body.
Sexing Females bigger and fuller bodied.

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 Unreported.
