The Corydoras Catfish, or Cory Cat, is an excellent addition to most community tanks because of their peaceful nature. Bottom dwellers, they are content to constantly rummage around the bottom of the tank looking for scraps. This is a very cute and endearing catfish with many different species available these days. They prefer to be in a school of 6 or more but many keep one or two in their smaller tanks. They do much better when kept in groups though. Cory cats enjoy feeding on tropical fish food that will sink to the bottom such as algae wafers or shrimp pellets.
