Pet's info: Fish | Unknown - Fish | Male | unneutered
My fish started to swim in circles and it looks like its tail has been broken. I would like to know wheter there is anything else that I can do, except for moving him to his own tank.

Move Patches to a smaller tank in case he has developed an infection. This will prevent spread to tankmates. Check the water quality for abnormal ammonia, nitrate or nitrite levels as well as improper pH. You can use a home test kit or submit a sample for testing. Most pet stores or aquarists will do this for free or for a nominal fee. Correct any imbalances as needed. Confirm adequate filtration in the main tank. Goldfish need powerful filtration to maintain good water quality. If you have more than one goldfish in the tank, you should have a 30-40 gallon tank minimum. If Patches has developed swim bladder issues, fast him for a day or two then feed small bits of shelled green peas. This should help after 3-4 days. If it doesn't, you will need to consider bacterial or fungal infections. This will require close examination for signs and symptoms to differentiate which so you can treat it properly. If you need to, request a consultation and we can discuss this further and in greater detail.
