Regularly monitoring goldfish is the best way to diagnose early signs of an illness. It’s easier then to notice changes in behavior and eating habits that are sure signs of a problem.

Understanding these signs is important so you can start treatment as soon as possible.

Note:  A sick goldfish may get black spots when the infection begins to heal.

3 causes of sick goldfish and how to recognise them

1. Overfeeding

Swim bladder problems cause a goldfish to float to the top of the tank. The problem is generally caused by overfeeding. It can be genetic, but diet is usually the culprit. It might be necessary to move the fish to a separate tank and reduce feeding to remedy the problem.
