BRONZE/ ALBINO/ VENEZULANUS BLACK/ VENEZULANUS ORANGE (Corydoras Aeneus)– I usually reserve Mondays to right about the common or easy fish that are available for fish lovers. None are more commonly seen in stores or easier to keep than the Bronze Cory. Unfortunately, picking this fish to write about forced me to review studies and paper on scientific names. The Bronze Cory has an enormous range throughout South America. Because of that, research teams have sometimes prematurely assigned names to fish found in different regions or with different color patterns. The name C. aeneus was assigned first, so all the other names that came afterwards are invalid if it is confirmed genetically. So far Corydoras venezuelanus, C. schultzei, C. microps, and C. macrosteus are no longer considered valid names as they were all synonyms for different populations of the Bronze Cory. That might be a little disappointing to hear particularly for owners of the Black Cory who might have hoped they had a rare cory species from Venezuela. In fact, the Black Cories were developed through the labors of Mr. Hartmut Eberhardt of Germany in the early 1990s. He bred them extensively so that, like the Albino Cory, their offspring would have the same coloration of their parents instead of reverting to the standard Bronze Cory form. Incidentally, there is another form of Black Cory now available that was derived from the Peppered Cory. You can tell the two apart easily because the black aeneus cory has reddish brown fins while the black peppered cory has a black or grey pattern on its tail and black fins. In any event, they are very easy to keep and are happiest in groups of 6 or more.
Origin: much of S. America and Trinidad
Size: 6-7.5cm/ 2.5-3in
Temperature: 21-27°C/ 70-82°F
Diet: Any food that falls or swims to the bottom. Please consider their needs when feeding your community tanks..don’t think of them merely as the clean-up crew. If you do that, they may not get enough to eat.
Habitat: The substrate should be sand or rounded gravel. Do not have sharp stones or glass in the gravel because it will injure their barbels and mouths which can lead to serious fungal infections.
Breeding: They attach their eggs to the sides of the tank or other aquatium surfaces, often after a water change if you refilled with slightly cooler water. They offer no parental care and if you want to raise most of the eggs, the parents should be removed or the eggs xhould be carefully scraped off and put in anogher tank with the same water as their original tank.
