Regular maintenance and water-quality checks help keep diseases away from goldfish, but illnesses still occur, even in the best-kept aquariums and ponds. The first sign of a problem may be a goldfish floating at the surface, by which time it is probably too late for effective treatment. For this reason , it is vital to set up a routine for examining fish; feeding time provides an ideal opportunity to check their appearance and behavior.
Fancy goldfish are more susceptible to different diseases, including bacterial, viral, and fungal, than the flat body type goldfish such as shubunkin and comet goldfish. As a result they are more prone to becoming ill and sick when kept in less than ideal conditions.
