When it comes to diagnosing cotton mouth in goldfish, there are two main routes – professional diagnosis and home-based observations. Both methods play a crucial role in identifying this common aquarium fish disease.

Professional Diagnosis

A professional diagnosis of cotton mouth is typically done by a fish veterinarian. These pros have the right tools and knowledge to identify various goldfish diseases accurately. They’ll perform a thorough goldfish health checkup, looking for telltale signs of cotton mouth like fuzzy, white patches on the fish’s mouth or body.
