Cloudy Eyes on Aquarium Fish

Cloudy Eyes on Aquarium Fish. Cloudy eyes on aquarium fish are a mid- to late-stage symptom of several fish diseases. When taken in context with other symptoms, cloudy eyes can help you correctly diagnose and treat the fish disease.

Symptoms

Eyes may be cloudy for different reasons, such as because of a film over the eye or cloudy from the inside-out.

Diagnosis

Cloudy eyes typically present with other symptoms. Because fish may have multiple diseases at the same time, it is important to assess the full range of symptoms collectively in order to treat the right disease.

Fish Tuberculosis

Fish tuberculosis is a progressive disease that starts with loss of appetite and hiding and evolves to rapid respiration, cloudy eyes, whiteish blotches, areas of raised scales, ragged fins and sunken abdomen. Treatment is difficult, so you should isolate the fish while you obtain and treat with the proper medications.

Bacterial Infections

Bacterial infections manifest in a variety of ways but frequently include a gray film over the eyes. Other symptoms of bacterial infections include rapid respiration, bloody scales, ragged fins and open sores. Treatment includes isolation of the infected fish and antibiotics.

Fish Flukes

Fish flukes are a parasite, and symptoms include cloudy eyes, rapid respiration, flicking and possibly worm-like attachments. Treatment includes a freshwater dip and proprietary anti-fluke medications.
