  • Points mostly on the head and mucous membrane
  • Fish are disoriented, apathetic and ill
  • Fish scrub the bottom of the pond to get rid of stains
  • Hardly any food intake recorded
  • increased mucus production and turbidity of fish mucus occurs

As a countermeasure, you should slowly raise the temperature in the pond to 30° C and keep it at least 10 Tege. In these conditions, the parasites are not viable. In addition, you should use malachite green. Also potassium permanganate and formalin help. With light infestation it helps the fish to bathe them in salt water.

Fin rot
  • mostly triggered by parasites
  • Almost all fish species can be affected
  • Fins fringe initially and later dissolve from outside to inside
  • quarantine infected fish - treat with antiseptic
  • Ensure the improvement of water quality when detecting the disease early
fish leeches
  • Eels live at the bottom of the pond in the mud layer - the thicker the layer, the more flukes
  • swimming fish are attacked - they are literally drilled and sucked
  • the disease can only be cured with medication
  • against Egel helps regular suction of the mud

Bacterial diseases

swash disease
  • Mushroom is taken with food (use only high quality food!)

  • Ulcers develop, break up and spread
  • In fish, balance disorders occur: he staggers
  • other signs: Apptitlosigkeit, emaciation to death
  • the disease is very contagious, a drug treatment is not possible

  • avoid organic deposit in the pond
  • If the disease is suspected, increase the flow in the pond
  • Disease untreatable - remove and destroy infected fish!
  • Remove and disinfect pond water (with lime nitrogen or chlorinated lime)

viral diseases

Ascites and goggles
  • Signs: bloated abdomen, eyes coming out of the head
  • Fish swim apathetically under the water surface and hardly eat
  • Virus can infect any fish
  • Fluctuations in water temperature and oxygen content promote eruption and spread
  • Food rich in vitamins and a low fish density can prevent the disease as far as possible
ConclusionMost fish diseases can be prevented by providing clean pond water. The values ​​must be checked regularly! However, you can also entrap diseases. Therefore it makes sense to first isolate newly purchased fish and observe them before giving them to the existing fish stock. Diseases can also be introduced by plants or birds and animals that visit the pond. You can not prevent everything.
