This is my new Skunk Corydoras Catfish, he had to learn to eat from the surface at the pet store because of his tank mates, and has since kept this behavior at home. So, for him to get plenty to eat, I stuck some flakes along the waters surface.
Corydoras catfish are generally docile fish that do well in a community setting.

Water Parameters: While Corydoras Catfish can do well in a wide range of water conditions, keeping the fish in established community tank water is a safe bet: Just some footage of my cory catfish swimming around and doing stuff.

Corydoras catfish are commonly kept in freshwater aquariums. They are from the genus and the family Callichthyidae. There are several different species that are all similar in size, bodyshape, and behavior. However, the different species have different coloration and markings. In somespecies their markings are quite striking. catfish have a labyrinth organ that allows them to breath atmospheric oxygen. In fact,they must have access to oxygen from both the air and from the water (they also have gills) or theywon't survive. Although corydoras are bottom dwellers you will frequently see them come to thesurface for a gulp of air. They are often referred to as armored catfish because they have two rows of bony plates on each side of their body. The upper part of their mouth has2 barbels, which can be seen in the above photo. The barbels are used to help locate food and sometimesfor feeling their way around the tank. They usually reach a size of between 2-3 inchesor 5-7.5 cm. There is one species that is very small even for a corydoras. It is the dwarfcorydoras (). It reaches a size of only 1 inch or 2.5 cm.Sexing corydoras catfish isn't always easy, but the females usually have wider bodies than males do. They usually spawn in groups of 3 (1 female and 2 males). They usually assume a T position. Beforereleasing her eggs, the female corydoras puts her mouth against the male's genitalopening and swallows some of the sperm. This passes through her digestive system unchanged very rapidly, and onto the eggs she has released and is holding in her ventral fins. After the eggshave been fertilized, the female corydoras carries them with her ventral finsto a flat surface in the tank, such as on plants or on the glass, where she sticks them. Theyhatch a few days later. Corydoras like to congregate together in the aquarium. They usually hang out together whilesearching for food and they even rest together. You will often see one catfish resting his head onthe body of another catfish. They don't even have to be the same species to get along andbecome friends. They only need to be of the genus . Because of their socialnature, you should not keep only one corydoras in your tank. You should always have atleast two, and 3 or more is even better (as long as you have the room in your tank). Corydorasdon't survive long alone. The Cory Catfish is a classic fish, found at almost every fish store, they are small, cute, active and altogether awesome pets!
