Cat-eLog Data Sheet
Scientific Name	**Corydoras aeneus** (Gill, 1858)
Common Names	Bronze Cory Albino Cory, Bronze Catfish, Bronze Corydoras, Kobberpansermalle (Denmark), Metallpansarmal (Sweden), Panzerwels (Germany)
Type Locality	Trinidad Island, West Indies.
Synonym(s)	Callichthys aeneus, Corydoras macrosteus, Corydoras microps, Hoplosoma aeneum
Pronunciation	Kory DOOR ass - ah NAY 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. Latin aeneus, brazen, of copper.

Species Information
Size	75mm or 3" 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. A very variable species. See catfish of the month link below. Occasionally confused with Brochis spp. but can be distinguished fairly easily by the number of rays and shape of dorsal fin - Corydoras have less than ten rays, Brochis have ten or more rays.
Sexing	Males are smaller (up to 65mm) and slimmer. Females grow larger and are much wider which can most easily be observed from above.

pH	6.5 - 7.5
Temperature	21.0-27.0°C or 69.8-80.6°F (Show species within this range)
Other Parameters	Generally should be kept at a temperature of around 24°C, water current should not be fierce.
Husbandry Information
Feeding	All prepared and suitably sized live foods are taken.
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. Avoid keeping over rough edged (chipped) gravel, this will increase this risk of damage the fishes barbels when it tries to dig.
Compatibility	A perfect citizen.
Suggested Tankmates	Keep in a shoal of at least 6 individuals - ideal first catfish for a beginner's community aquarium.
Breeding	Easily accomplished with captive raised stock. Some colour varieties are more challenging than others. Given the presence of a suitably egg-laden female and a mature male or two, spawning can be triggered by a large, cool water change. Try changing 30-40% of the aquarium water (at 21°C) and bring the temperature down to 16°C. Do this slowly over an hour or two.The fish should respond by spawning in the classic 'T' formation method. Here, using one of his pectoral fins, the male clamps the female to his side by her barbels and fertilizes a small batch of eggs held within the protective basket formed by her pelvic fins. The adhesive eggs are then placed on plants or aquarium walls and the process repeated. The eggs take 3-4 days to hatch. It is safe to leave well fed parents with the eggs, but some breeders prefer to remove the eggs, or indeed parents, to avoid any temptation of an easy snack. For the first few days of their life, pre-soaked powdered flake food should be fed to the fry. After the first 3 or 4 days, newly hatched brineshrimp can also be sparingly used to bring on the fishes growth. As the fish grow more and more foods can be offered in line with the size of the developing juveniles. Adult colouration is reached in around nine weeks.
