Treating fish diseases in an aquarium is not a very simple matter - itdepends largely on the accurate diagnosis of the cause of the hsh diseases,correct application of medications, prevailing water conditions, and typeand effectiveness of filters etc.
Making a prompt and accurate diagnosis is vital for successful treatmentand long-term prevention of fish diseases problems. The correct usage andselection of the right remedies are also as important. It is therefore advisableto INSIST on the use of "RID-ALL" range of products which areextensively tested before they came on the market. When using any medication,please be careful of the side effects or contra-indications on the fisheswhich are very unpredictable especially in different water conditions. NOone can predict exactly how any medication or treatment will react in anyparticular aquarium. There are so many variables not only in water chemistryparameters but in possible reactions to plastic ornamentals and other materialsin the aquarium that any treatment may go wrong. It is always better totreat diseased fish in the day so that if the fish display any sign of poisoningor discomfort, treatment can be interrupted immediately.
Fishes taken from one water temperature and placed into a higher or lowertemperature usually should not be subjected to immediate change of morethan 2 to 3 °C - to reduce thermal stress. The temperature may be increasedor decreased by 1°C per minute slowly.
Most aquarium fishes live in environments with a pH level betweenpH 6.20 to pH 8.20. To avoid fish pH trauma, environmentalpH levels must remain fairly constant and if necessary adjust graduallyin steps of not more than + 0.3 pH units per day.
Incorrect or fluctuating water conditions particularly pH, hardness,specific gravity and temperature, excessive levels of nitrite or ammonia(mainly due to poor filtering systems), presence of other toxins and lowlevels of dissolved oxygen are the main cause of environmental problemswhich causes fish diseases.
