Most aquariums are suitable for keeping one type of catfish or another. Catfish range in size from small to very large so a species suitable to live with the fish you already keep will not be hard to find.
There are many other differences between catfish besides their size. Some such as glass catfish will be best kept as a school as they swim in the midwater. Others such as the bristlenoses and plecos are more suitable as a solitary catfish.
What catfish do have in common is their sensitive whiskers which have inspired their name. These barbels are used to sense food in the substrate as they pass over it's surface.
Most people will be familiar with the small sucker mouth catfish sold in pet shops to clean the aquarium glass. These are easy to breed and inexpensive. At the other end of the scale Plecostomus are a magestic looking large catfish that can sell for more than $100.
Why People Choose Catfish
The algae cleaning abilities of many species have made them a very popular fish. Most also contribute to the aquarium's cleanliness by cleaning excess food from the gravel before it purifies. Catfish are also generally very hardy with a tolerance for a wide range of water conditions. All of these properties and more make catfish a great choice for community aquariums.
