Corydoras concolor • Callichthyidae • Cat-eLog

Cat-eLog Data Sheet
Scientific Name	**Corydoras concolor** Weitzman, 1961
Common Name(s)	Slate Cory
Type Locality	Las Mangas, in a trib. of Río Parguaza, Bolivar, Venezuela, 6°20'N, 67°10'W.
Pronunciation	Kory DOOR ass - CONN cull or
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. Latin concolor = coloured uniformly.
Species Information
Size	60mm (2.4") 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. Easy to identify, this round nosed, high backed species is all over slate grey.
Sexing	Males have a longer dorsal, and they are somewhat smaller in proportion than the more robust females.
Habitat Information
Distribution	Western Venezuela Orinoco (click on these areas to find other species found there) (Click the map-icon to show/hide map of species distribution)
pH	6.4 - 7.0
Temperature	23.0-26.0°C or 73.4-78.8°F (Show others within this range)
Husbandry Information
Feeding	The usual fare for adult Corys, a good quality flake food, tablet food, frozen bloodworm and whiteworm used sparingly. I fed the fry with infusoria to start off the first few days, then on to Brine shrimp nauplii, Microworm, fry and crushed flake.
Furniture	Planted tank with a few hideaways; that way they will feel secure in their environment, and you will see them out in the open more often.
Compatibility	Peaceful
Suggested Tankmates	Certainly will enhance your community tank as long as it is at least 24'' long with 36'' being a better option. The usual community fish will suffice, but I am suspicious of a few of the Barb family as they do tend to nip the dorsals of Corydoras, so pick carefully.
Breeding	Using a 18'' x 12'' x 12'' tank with sand, Java moss, Java fern and a sponge filter. They spawned at a water temperature of 78F, a pH of 6 and GH 1. The eggs (shown above) are quite large, measuring 2mm and a creamy white colour. The first spawning yielded only 8 eggs but the second, 7 weeks later, amounted to 25 eggs. They laid eggs on and off for the next year then suddenly stopped for a year. The fry look like any other Cory fry having spots over the top half of the body and gradually begin to resemble the parents after 6 weeks, with pale orange fins, and a dark head which has quite a steep incline, making it look quite chunky.
