Corydoras sychri • Callichthyidae • Cat-eLog

Cat-eLog Data Sheet
Scientific Name	**Corydoras sychri** Weitzman, 1960
Common Name(s)	Long nosed fairy catfish
Type Locality	South America, specific locality unkown (aquarium specimen) [apparently Prov. Maynas, Rio Nanay, right bank near Shiriyana, Peru.]
Pronunciation	Kory DOOR ass - sigh cry
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. Named to honour Mr. Al Sychr.
Species Information
Size	65mm (2.6") 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 confused with C97. In C. sychri the head shape is longer, with a distinct angular profile from dorsal to top of head above the eye and then down to the snout. Some specimens may even show a curve to the snout, making it more of a saddle shape. C97 has a shorter, straighter profile. The body spotting is more like small blotches rather than defined spots in C. sychri, but in C97 the spots are usually well defined, fewer, and more evenly spaced out. If you compare the colour patterns to those of C. loretoensis (C. sychri) and C. atropersonatus (C97) may better explain the differences, but always allow for a certain amount of variability.
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.
Habitat Information
Distribution	South America: Nanay River basin, Loreto, Peru. Amazon, Upper Amazon, Nanay (click on these areas to find other species found there) (Click the map-icon to show/hide map of species distribution)
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	Unreported.
