Corydoras cochui • Callichthyidae • Cat-eLog

Cat-eLog Data Sheet
Scientific Name	**Corydoras cochui** Myers & Weitzman, 1954
Common Name(s)	C022, Barredtail Corydoras, Cochu's Catfish
Type Locality	Rio Araguay, Santa Maria Nova, Goyaz, Brazil.
Pronunciation	Kory DOOR ass - COCK oo 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 is named in honour of Mr Fred Cochu.
Species Information
Size	35mm (1.4") 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	The males tend to be more slender than the females.
Habitat Information
Distribution	South America: Upper Araguaia River basin. Amazon, Lower Amazon, Tocantins, Lower Tocantins, Araguaia, Upper Araguaia (click on these areas to find other species found there) (Click the map-icon to show/hide map of species distribution)
pH	6.0 - 7.2
Temperature	23.0-26.0°C or 73.4-78.8°F (Show others within this range)
Other Parameters	2-25°dGH
Husbandry Information
Feeding	Readily accepts a mixed and varied diet which includes granular foods, frozen bloodworm and good quality flake to name but a few.
Furniture	Plenty of hiding places amongst bogwood and rocks. The ideal aquarium substrate to use with these catfish is aquarium sand.
Compatibility	Peaceful.
Suggested Tankmates	Wherever possible I would recommend that the aquarist keep these catfish in a community aquarium in small groups of six or more, but as the absolute minimum I would suggest three specimens assuming that they are available in these numbers. In their natural habitat Corydoras cochui would be found in relatively large shoals.
Breeding	There are documented reports of aquarium spawnings of Corydoras cochui, adopting the typical ?T shape? breeding clinch. The spawning activity follows on from a period of conditioning with foods such as Daphnia and bloodworm, and a partial water change using cooler water.
