Abnormal behavior and etiology of colorful diseased fish

General colorful diseased fish we can roughly understand its possible cause by abnormal behavior, appearance and so on.

Abnormal behavior of diseased fish and its causes:

1. The fish floats to the surface, slow and listless-lack of oxygen, Gill parasites and bacterial infections.

two。 The feeding rate falls to the bottom-the water quality may deteriorate.

3. Set in a corner of the bottom of the cylinder, shrinking fins, etc.-there may be internal and external parasites, bacterial infections, etc.

4. Friction cylinder wall or heating tube-external parasite infection.

5. Convulsions-caused by internal or external parasite infection or poor water quality, wrong pH value.

6. Hanging upside down, head and tail, out of balance-brain infection, swim bladder or kidney inflammation.

7. Gill cover open, shortness of breath-Gill parasites and bacterial infections.

Symptoms of appearance and possible causes:

1. Darkening of body color-intestinal bone discomfort or indigestion; Gill parasites, external parasites, internal parasites and viral infections.

two。 Weight loss of fish-hexaflagellosis, capillary nematode, streptococcosis and tuberculosis.

3. Abdominal swelling-parasitic and bacterial inflammation or food rancidity swelling.

4. Fin damage and erosion-oral filariasis, bacterial fin disease.

5. Dark eyes-internal parasites, internal inflammation.

6. Exophthalmos-caused by nephritis, tuberculosis and cylindrical trematodes.
