Ich is a common parasitic disease that affects gars. It is caused by a protozoan that attaches itself to the skin and gills of fish. Symptoms of ich include white spots on the body, flashing, and rubbing against objects.
Bacterial Infections
Gars are also susceptible to bacterial infections, such as Aeromonas and Pseudomonas. Bacterial infections can cause a variety of symptoms, including skin ulcers, lethargy, and loss of appetite.
Fungal Infections
Fungal infections, such as Saprolegnia and Achlya, can also affect gars. Fungal infections can cause cottony growths on the body and gills of fish.
Did you Know ?
Gars are known for their ability to breathe air. They have a special respiratory organ called a swim bladder that allows them to take in oxygen from the air and use it to breathe. This ability allows gars to survive in low-oxygen environments, such as stagnant pools or shallow lakes.
