The Goldfish Parasite Chilodonella Chilodonella is a prevalent ciliated protozoan parasite and a common killer of goldfish. Under a microscope the chilodonella parasite appears leaf or heart shaped with a granular inside and a pharyngeal basket that appears as a clear bubble on the front side of the organism.
Chilodonella cyrini is another microscopic protozoan that can be deadly to freshwater fish. The protozoan is an accomplished swimmer, and can quickly infect an entire pond’s stock of koi fish. In ponds with large populations, it can spread quickly and be devastating—especially to younger fish.
Chilodonella tolerates a wider variety of different water temperatures than many other parasites and ore often found in colder waters. The disease is as I said earlier easy to treat once diagnosed and can be cured with a wide variety of treatments ranging from commercial Chilodonella medicine to treating the water with (or bathing the fish in) potassium permanganate, formalin, malachite.
Chilodonella definition is - a large genus of freshwater or brackish water holotrichous ciliates that are ovoid and dorsoventrally flattened and that include a number of ectoparasites some of which are destructive pests of the skin and gills of cyprinoid fishes.
Chilodonella cyprini was found in large numbers on the skin and gills of Cyprinus carpio, Aristichthys nobilis, Ctenopharyngodon idella, Mylopharyngodon piceus, Salmo irideus, Perca fluviatilis, Leucaspius delineatus and Pungitius pungitius in various regions of the USSR at water temperatures of 0.5 to 18 deg C; Chilodonella hexastichus was also found, for the first time in the USSR, on A.

Heart-shaped ciliate (e.g., C. cypriniof carps) of about 0.07 mm in size, which lives on the skin and gills of fish and leads to the production of slime and eventually to death due to the lack of.
