Characterized by reddening of the anus, slimy, bloody and thread-like feces. Fish will involuntarily rise to the surface because of the buildup of gases in the intestines. Fish become lethargic, turn a dark color, but they do not show a loss of appetite.
An autopsy and examination of the gastrointestinal tract are necessary to make the final diagnosis. Mucous membranes are inflamed, with a large number of bleeding spots. To rule out infectious diseases microbiological and parasitologic examinations are performed.
This disease is most common in adult fish that eat unvaried, concentrated food. Feeding fish low-quality food, high amounts of fry food, and unwashed or partially decayed Tubifex or bloodworm causes the disease.
How to cure:
Stop feeding for a week, then switch to moderate feeding by high-quality varied food. The therapeutic dose of sodium chloride is added into the aquarium. Perform a regular water change, remove food remnants from the gravel.
Provide fish with a balanced diet. Give vitamin supplements.
Fish must not be given low quality live food caught in polluted ponds, Daphnia, Gammarus, bloodworms and Enchytraeus albidus - Enchytraeus. Dry foods are difficult to digest and they cause inflammation of the mucous membrane of the gastro-intestinal tract. Feed your fish live hydrobionts.
Fish susceptible to the disease/disorder:
Adult fish are particularly susceptible.
