Diseases

One of the most trying times that you will need to face as an aquarist is when your fish
fall ill. This is bound to happen at one time or the other. Since you are trying to recreate
an open and unlimited ecosystem within the confines of your 50 or 60-gallon / 200 L
aquarium, there are many things that can go wrong. Many of these ailments cannot
actually be termed a disease. The symptoms shown by the fish are merely reactions
against improper conditions in the aquarium. These conditions can range from improper
water chemistry to the actual presence of undesirable parasites in their water. It is
possible to keep your fish stress free and disease free if you provide them with the right
environment, the right water chemistry and the right kind of food.
