How to Cure Discus Disease

Discus fish add beauty to any freshwater aquarium. However, their susceptibility to several diseases earned them a reputation of being difficult to take care of. Discus disease can strike your tank anytime, but by identifying symptoms at an early stage of the disease and by taking the necessary action, your chances of saving your fish are good. But the best way of reducing the risk of discus diseases is to keep your fish in an ideal environment, which usually means right temperature, suitable and correct water composition, low levels of nitrogenous waste and proper diet.

Instructions

    • 1

      Test the water quality the moment you see signs of disease or unusual behavior among the discus fish.

    • 2

      Ask your dealer or a vet if the fish in your tank can tolerate the treatment, because certain medications may cause harmful reactions to a number of discus fish.

    • 3

      Get the dose right according to the volume of your tank and seek the advice of a vet. Certain pathogens will develop resistance once you don't add enough treatment, thus making the disease more difficult to treat.

    • 4

      Increase temperature of the water from 30 to 36 degrees C for the next two days, and keep it at 36 degrees C for the next eight to 10 days if the discus develops a hole in the head or if it has White Spot, Velvet or Costia. Administer Metronidazole orally once in three days when the case is severe or if the fish has internal parasites. Feed it with medicated food every two to three days for the next 10 days. Otherwise, force feed the fish using a syringe without the needle if it has stopped eating.

    • 5

      Move the fry to another aquarium as soon as they are big enough to feed on something else so that they won't have to subsist on secretions from the parent discus fish that may have developed gill flukes. Do not let fry aquariums get crowded.

    • 6

      Use Chloromycetin to eliminate bacterial infections. Buy it in powder form and put 1 tsp. of it for every 100 liters of water.

    • 7

      Increase the aeration and add an extra airstone or two to increase the oxygen supply, as many diseases cause gill problems.

    • 8

      Remove treatments from the aquarium using a chemical filter media. Remember to remove them or switch them off during treatment.
