Fish and Aquarium

The best way to keep your fish healthy is
to follow the basic rules of good aquarium or pond management. Learn how to set up your fish tank properly. Feed your fish
correctly, keep their environment clean, avoid rapid temperature changes,
ensure there is an adequate oxygen supply and make partial water changes as
necessary.

Unfortunately, illness sometimes still
occurs and the first sign to be aware of is stress. Just as a stressed human is
prone to infection by bio-aggressors, so are fish, and stress is the principle
cause of disease in fish.

There are three basic types of diseases
in fish: parasitic, bacterial and fungal. These organisms are always present in
the aquatic environment and a healthy fish can generally ward off, however, if
a fish is weakened by stress or damage the risk of infection is high.

When fish become ill they show signs in
their behavior such as:

• clamped fins
• shaking bodies
• constant scratching against objects in the tank
• 
  hiding in the corners
• gasping at the surface
• swimming abnormally

Treatment is often available for common goldfish diseases. See you local pet store and remember to treat any diseases promptly so that the whole aqauarium is not affected by the disease.
