Beginners Guide - Catfish.

Cory Cats
Members of the family Callichthyidae, a family of armored catfish from South America. Corys are small (generally 2 1/2" long or less), schooling fish that are always searching the bottom of the tank for food.

There are at least 140 species of catfish in the genus Corydoras. Some of these are quite delicate and die quickly even in the hands of experts. The fragile ones, however, are rarely seen in pet stores and are high priced when they can be found.

The Corys you will see for reasonable prices are hardy and can even survive in a tank with low oxygen as they can swallow air from the surface and absorb it through their intestines. Some Corys you may encounter are the Bronze Cory - C. aeneus, the Spotted Cory - C. ambiacus, the Leopard Cory - C. julii, the Skunk Cory - C. arcuatus, the Bandit Cory - C. metae, and the Panda Cory - C. panda.

Corys generally feed at the bottom of the tank and special sinking foods should be fed. These include sinking pellets like Tabi-Min and frozen blood-worms. Care should be taken to insure that all frozen foods are eaten quickly as they decay rapidly and can foul the tank.
Don't overfeed!
