Cory Catfish

Unlike many types of catfish, Corys remain relatively small as adults. In fact, most only grow to between 1" and just over 4" in length, which suits them to smaller freshwater community aquariums. However, since most Cory Cats prefer to be kept in groups of four or more, these active scavengers also attend to the substrate cleaning needs of larger aquatic systems.
In addition to their smaller size, most species of Corydoras are active during daylight hours. This allows aquarists ample time to observe their antics, in comparison to the nocturnal habits of most types of catfish. Plus, there are over 140 identified Corydoras species, each in an array of body shapes and colorations, which ensures there is a Cory Cat suited to any aquarium's style.
