My goldfish has been suffering from some type of hole in the head. I thought it may be from bacterial infection, so I've treated him with tetra fungus guard(nitrofurazine furazoldone, potassium dichromate) a fungus and bacteria med. This is the end of second treatment. It seems to have gotten worse. Am I treating him properly? Do I need a different type of med? Is this goldfish head rot? Any help would be great, had this guy 3 years and don't want to lose him. Thanks.
The hole is white with a red sore deep inside crevice.
