Scientific NameCorydoras concolor  Weitzman, 1961
Common NamesSlate Cory
Einfarbiger Panzerwels (Germany)
Type LocalityLas Mangas, in a trib. of Río Parguaza, Bolivar, Venezuela, 6°20'N, 67°10'W.
PronunciationKory DOOR ass - CONN cull or
EtymologyCory = 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.

Size 60mm or 2.4" SL. Find near, nearer or same sized spp.
IdentificationCorydoras 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.
SexingMales have a longer dorsal, and they are somewhat smaller in proportion than the more robust females.

FeedingThe 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.
FurniturePlanted 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.
Suggested TankmatesCertainly 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.
BreedingUsing 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.

Registered Keepers(1) mummymonkey (k: 7), who also notes: "Like a large tank and plenty of hiding places. Easily spooked. Let the water age for 3 or 4 weeks to induce spawning. Spawned when water was left to age for 3 or 4 weeks.
