QuestionI have a red head goldfish, it keeps flipping and rolling to one side, any suggestions on what it might be.
AnswerHey Lee
It sounds as though your goldfish has swimbladder disease.

Scroll down on that website page above and find the bit on swimbladder. Treatments are on there.
Good Luck and hope this helps Jack
