What to do if you if a fish gets ill?

If you suspect that you have a fish that’s ill in the tank there are certain procedures you can take to prevent it spreading to other fish or getting worse. You would need to consult a professional depending on what illness or disease it has. The treatments range from simply applying medication or the use of a special drug maybe needed to get rid of parasites or funguses. It’s always best to consult a professional as it may be something simple to cure, for example by adding an air pump to help circulation through out the tank if its down to lack of air.
