The proper species must be chosen while keeping a catfish as a pet. Most of the worries regarding keeping pet catfish come down to size, even if certain species may have been illegally imported and shouldn't ever be kept in your aquarium. All fish increase in size, however certain catfish species are considerably better suited to huge public aquariums than most home aquariums. To guarantee that your catfish will live a long and fulfilling life, be sure to conduct your study on the species you wish to maintain.
What is a Catfish?
Despite having different sizes, catfish are all bottom feeders, have similar shapes, and are most active at night. The absence of scales and smooth skin are two distinguishing features of catfish. The fins, backs, and sides of catfish are instead covered in incisive spines.
Their mouth-area whiskers, also known as barbels, which give the fish a catlike look, are their namesake and most distinctive characteristic. Eight barbels may be seen on many different kinds of catfish, and all have at least one pair.
The majority of catfish species have an excellent sense of smell, which aids in hunting in murky waters. Catfish may grow to a length of 15 feet (4.6 meters), or 4-5 centimeters. Although they come in a variety of colors, most have subdued, boring tones.
