Bacterial Infection
Other Names: Pseudomonas,Vibrio
Symptoms: Reddened, frayed fins with open sores, rapid respiration, cloudy eyes, poor appetite, lethargy, weight loss, abdominal swelling.
Comments: This disease is usually associated with stress, sometimes brought on by poor water quality. Healthy animals can usually resist infections.
Treatment: Identify the source of stress and correct the problem. If this does not correct the problem, the animal should be treated with antibiotics in a hospital tank. Adding antibiotics to the main aquarium can kill invertebrates and damage the biological filter.
Prevention: Insure good water quality and temperature parameters to prevent animals from getting stressed. Stress breaks down the protective mucous coating on a fish and allows bacteria to gain a foothold. The use of an ultraviolet sterilizer may help prevent outbreaks of this disease.
