ABOUT CLOWN KNIFEFISH
The Clown Knifefish (Chitala ornata), also called the Spotted Knifefish or Clown Featherback, is a large tropical freshwater fish native to Southeast Asia. Its body is long, deep and strongly compressed from side to side, creating the distinctive blade-like shape that gives knifefishes their common name.
Adults develop a row of large black spots ringed with white along the rear portion of the body. A long anal fin extends along much of the underside of the fish and moves in a wave-like motion, allowing the Clown Knifefish to glide smoothly through the water.
Clown Knifefish are predatory and become especially active around dusk and at night. Their natural prey includes fish, crustaceans and insects. Layton Aquarium notes that they will attempt to eat fish small enough to fit into their mouths.
These fish can also survive in water with very little dissolved oxygen. Clown Knifefish are obligate air-breathers and regularly rise to the surface to breathe atmospheric air.
Care & Conservation
Clown Knifefish are currently classified as Least Concern. Healthy rivers, lakes, deep pools and seasonally flooded forests remain important to the species. Protecting Southeast Asian freshwater ecosystems helps support Clown Knifefish and the many other animals that depend on these connected habitats.
