Family
Common name: Eeltail catfish
Scientific name: Plotosidae
The Plotosidae family, commonly known as eeltail catfish, includes a variety of species well-suited for the larger home aquarium. These catfish are known for their elongated bodies that taper to a point, resembling an eel's tail. They are generally hardy and adaptable to various water conditions, making them a good choice for intermediate aquarists. Eeltail catfish are nocturnal and can be quite active at night. They are also known for their ability to tolerate lower oxygen levels due to a modified intestinal tract that functions similarly to a lung. In the wild, they are found in a range of habitats from freshwater to brackish environments, but in the aquarium, they typically prefer a marine setup.
