The Upside Down Catfish or Synodontis nigriventris gets its name because it is seen in an aquarium swimming upside down and even feeding upside down on the surface! This odd behavior makes them a favorite among aquarium enthusiasts, and one of the strangest species of Catfish in the world.Also known as the Blotched Upside Down Catfish, this freshwater fish can grow to about 4" in length, and originates in the Congo Basin. This fish has black and white splotches that cover its body, and the classic Catfish barbels on its mouth.
The Upside Down Catfish is considered to be very hardy, and can survive in an aquarium of 30 gallons or more with lots of plants, and hiding spaces. The following water conditions are acceptable, 75-82° F, KH 4-12, and pH 6.0-7.5. They can be fed an omnivorous diet consisting of freeze-dried bloodworms, tubiflex, flake food and pellet food. The Upside Down Catfish also doubles as an aquarium cleaner, eating the algae that grows in a heavily planted aquarium. Check out the Upside Down Catfish swimming in the the video below...
