Bacterial infection covers a range of goldfish illnesses, with varying causes. Dirty water and/or cold water, overcrowding and corn-based diets can lead to bacterial infection.

There are four types of goldfish bacterial infections.

o Fin rot - resulting from environmental stress
o Bacterial body ulcers -lesions on the goldfish's body
o Bacterial gill disease - in which the gills are the primary target
