Treatment: If the fish suffocating on the surface, or have purple gills, then the cause may be high levels of ammonia (nitrites, nitrates) or low oxygen levels. In the first case it is necessary to replace the water (but not more than one-third volume at a time), and the second is to improve the operation of the aeration system (to wash filters).
If in case the abnormalities of pH or hardness, it is necessary to replace about one third of the volume of water and continue to conduct regular water tests on these indicators.
Disease belostotski (freshwater scabies).
Symptoms: the fish has grains of salt, fish behaves nervously and rubbing against aquarium decorations.
Treatment: the disease “white spots” (Ichthyopthirius multifiliis) is called a parasitic protozoan. To cure aquarium fish from the disease and prevent the re-emergence of the parasite it is necessary to arrange a week-long quarantine. Fish is deposited in a separate quarantine tank where they are treated until the disappearance of the white point with the help of medications that contain formalin or malachite green. In the main tank at this time supported stable temperature (25-30 degrees), and medications, it does not add. Finding no victims, the parasites die within 3-4 days.
Symptoms: the fins of the fish become pale and die. Fin rot often follows damage to them. It can also be caused by poor water quality.
