Chitala

Chitala is a genus of ray-finned knifefishes belonging to the family Notopteridae. These fish are native to freshwater habitats in South and Southeast Asia. Species within the Chitala genus are characterized by their elongated, knife-like bodies, small dorsal fins (often absent), and long anal fins that extend along the underside of the body, facilitating graceful, undulating swimming. They are typically nocturnal predators, feeding on smaller fish, crustaceans, and insects.

The most well-known species within the genus is arguably Chitala chitala, commonly known as the clown knifefish or spotted knifefish, a popular aquarium fish despite its large adult size. Other Chitala species include Chitala ornata (ornate knifefish) and Chitala lopis (Indonesian knifefish).

Chitala species are sometimes used as a food source in their native regions, and their unique appearance makes them valuable in the ornamental fish trade. However, overfishing and habitat destruction pose threats to some populations. Conservation efforts vary depending on the specific species and geographic location.
