Cat-eLog Data Sheet
Scientific Name	**Corydoras arcuatus** Elwin, 1938
Common Name(s)	Arched Cory, C020
Type Locality	Amazon R. (aquarium specimen)
Pronunciation	Kory DOOR ass - arr kew ATT uss
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 refers to its bowed (arcuatus=bowed, as in bent like an archer's bow) colour pattern.
Species Information
Size	55mm (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. The colour pattern forms an even arch (hence the scientific name) of dark stripe from the snout to the lower back.
Sexing	Females larger and fuller bodied.
Habitat Information
Distribution	Widespread throughout the Upper Amazon region. Amazon, Upper Amazon (hover or click on these areas to show maps or find other species found there)
Temperature	22.0-26.0°C or 71.6-78.8°F (Show others within this range)
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. Do not keep over regular, not rounded gravel, this will damaged the fishes barbels when it tries to dig.
Breeding	Has been bred in captivity.
